Other Loud family members
Leonard Loud (voiced by Rick Zieff) is Lynn Sr. and Lance's father, Rita and Sharon Loud's father-in-law, and the children's paternal grandfather who was mentioned by Lynn Sr. in "Vantastic Voyage". He is often called "Gramps" by his grandchildren. Like his son, Leonardo tends to cry a lot. While originally designed to look like a hippie in a flashback seen in "Vantastic Voyage", he was later redesigned in his official debut in "Camped!" where he resembled Lynn Sr. with a longer beard. Leonard was originally a traveling fisherman as seen in "Camped!" until he got word from his son when Camp Mastodon was closing. When the treasure was found and he used his boat to save his family, Leonard offered to use the treasure to keep Camp Mastodon open as its new proprietor so that he can be closer to his family. In "Present Danger", it is revealed that Leonard is a fan of David Steele. In "Bummer Camp", Leonard learns how to be a camper from his grandchildren. The episode "Be Careful What You Fish For" revealed that Gramps lost the big toe on his right foot 30 years ago during an attack by the great white sturgeon Moby Rick who also wrecked the ship that he was on. Lynn commented that the loss of his big toe is why he wears socks and sandals.
Lance Loud (voiced by Rob Riggle) is Lynn Sr.'s athletic brother, Rita Loud's brother-in-law, and the children's paternal uncle who lives out in Petoskey Falls, Michigan where he is the proprietor of the Endur-Lance Gym. However, there are things he can't do because of his muscle mass like ziplining and swimming. He is first mentioned in "Home of the Fave" and made his first physical appearance in "'Twas the Fight Before Christmas". Compared to his brother Lynn, Lance has a rather muscly build. He has a wife named Sharon and raises three children: eldest son Shane, middle daughter Shelby, and youngest son Shiloh. In "Home of the Fave", Lance was mentioned to be the favorite son of Leonard and during a family Christmas gathering, an accident would drive them apart. During "'Twas the Fight Before Christmas", Lincoln along with his sisters would devise a plan to reunite his father with his brother at Camp Mastodon. Eventually, Lynn Sr. and Lance reconciled after working together to save Lincoln, Lori, and Shelby who were stranded on a swiftly-cracking sheet of ice at Lake Mastodon. In "One False Move", Uncle Lance moves his family to Royal Woods to be closer to the Endur-Lance Gym as they move in to the house on the same street as their relatives. In "Grouse of Horrors", Lance is shown to have a fear of ghosts and can make "Lance-sagna" (his take on his brother's Lynn-sagna with more protein powder").
Sharon Loud (voiced by Ozioma Akagha) is an African-American woman who is Lance's wife, Lynn Sr. and Rita Loud's sister-in-law, and the children's paternal aunt. She is an expert at yoga and meditation. Sharon makes her first appearance in "'Twas the Fight Before Christmas" where she was shown to be close with Rita. When her husband Lance got enraged when he saw his brother Lynn, Sharon taught him a method to stay calm which he eventually took into heart later in the episode.
Shane Loud (voiced by Christopher Livingston) is the oldest son of Lance and Sharon and the children's paternal cousin. He makes his first appearance in "'Twas the Fight Before Christmas". Like Luna, he is into singing and is able to do a cappella.
Shelby Loud (voiced by Kyrie McAlpin) is the bespectacled middle child of Lance and Sharon and the children's paternal cousin. She makes her first appearance in "'Twas the Fight Before Christmas". Like Lincoln, she is the only daughter in the family and can be silly at times. When brainstorming, Shelby tends to twirl around the room. She is shown to have a bad sense of direction.
Shiloh Loud (voiced by Bahia Watson) is a 6-year-old child who is the youngest child of Lance and Sharon and the children's paternal cousin. He makes his first appearance in "'Twas the Fight Before Christmas". Shiloh is known to do cannonballs into any physical object and can lift objects much larger and heavier than he is.
Albert Reynolds (voiced by Fred Willard in 2016–2019, Christopher Swindle in "Resident Upheaval", Piotr Michael in 2021–present, portrayed by Bill Southworth in A Loud House Christmas) is the children's maternal grandfather, Lynn Loud Sr.'s father-in-law, Rita's father, and Ruth's brother. He is often called "Pop-Pop" by his grandchildren. It is revealed in the series that he was a former member of the United States military until his retirement. Albert wears a white button-up shirt, blue jean overalls with orange suspenders, a black belt, and white sneakers. He has a good relationship with his daughter and is very close to Lincoln, with whom he shares the same hair color and hairstyle. While it was revealed in "Cover Girls" that Albert is near-sighted, this is never brought up again in later episodes. Starting in "The Old and the Restless", Albert moved into Sunset Canyon Retirement Home where his old friends live. In "Pop Pop the Question", he proposes to Myrtle, and they are officially married in No Time to Spy: A Loud House Movie.
Myrtle (voiced by Jennifer Coolidge in 2018–2022, Alex Cazares from 2024 onwards) is the girlfriend of Albert. Because she traveled extensively in her youth prior to meeting Albert, Myrtle never married or had children of her own. When she became Albert's girlfriend, she started to treat the Loud children as her own grandchildren. Upon accepting her, the children started to call her "Gran-Gran" as she had wanted them to call her. The episode "Resident Upheaval" reveals that Myrtle does not live at Sunset Canyon Retirement Home and only visits Albert there. By the end of the episode, Myrtle moves into Sunset Canyon Retirement Home with Gayle as a roommate. In "Pop Pop the Question", Myrtle proposes to Albert while officially becoming the Loud children's official step-grandmother. It is also revealed that when she was younger, she was a secret agent who was in fake marriages with her partners as part of her cover on different missions. Her skills do help Lincoln perfect his spy tumbling. The film No Time to Spy shows her marriage to Albert and revealed that her spy code-name is Agent 28.
Ruth (voiced by Grey DeLisle) is Albert's sister, Lynn Loud Sr.'s aunt-in-law, Rita's paternal aunt, and the Loud children's maternal great-aunt. She is depicted as a cat lady with a distasteful attitude because she makes the children eat old pudding and watch her cats when the Loud family visits. She wears an olive green dress with flowers on it and white shoes. Ruth is also shown to have a sixth toe on her left foot which creeps out even Lynn Sr. Only Rita, Lana, and later Lily are the ones who can tolerate visiting her.
The ancestors of the Loud family from the 1600s, shown in The Loud House Movie, were driven away from their town of Loch Loud by Aggie using a magic stone on Lolo the Dragon. While Lucille first appears as a ghost in the film, the rest of them appear in ghost form at the end of the film to praise Angus for taking on the responsibility as the new Duke of Loch Loud.
The Duke of Loch Loud (voiced by Asher Bishop) is the unnamed ancestor of the Louds, who looked like Lincoln, and was known for his noble deeds around Loch Loud. Following Morag's defeat, the ghost of the Duke and his family deem Angus a worthy successor of Lincoln as the new Duke of Loch Loud.
Lucille Loud (voiced by Katy Townsend) is an ancestor of the Louds, looking like Lucy, and being one of the sisters of the Duke of Loch Loud. She serves as a witness chronicling the Loud family's past after being summoned into the present by Lucy in ghost form. She is also the only distant ancestor of the family whose name has been revealed.

A Lori look-alike 1600s' ancestor who wears a sleeveless dress, and one of the sisters of the Duke of Loch Loud.
