Partly for fun, partly for little fun facts: list of the Sinners who have siblings (either canonically to Limbus or from their source material)

Confirmed in Limbus:

Hong Lu: Jia Huan obviously, but in the original book they also have 3 other siblings who Hong Lu mentions sometimes in his anectodes.

Gregor: had his little sister Grete mentioned briefly in Canto I though not by name, implied to be dead but actual whereabouts and fate are unknown currently.

Sinclair: had an older sister (funnily enough had two sisters instead in the book but in Limbus only had one, probably for simplicity's sake)

Not confirmed canon to Limbus but part of their source material/inspirations:

Rodion: had a younger sister named Avdotya or "Dunya" for short who lived together with their mother. Similarly confident as well as caring towards Rodion. Worked as a governess (basically a private tutor) to help with her family's poverty, being close to trying to marry to get them out of their situation which served as further motivation for Rodion's murder.

Yi Sang: the real author Yi Sang was the eldest son of three children, having one younger sister and one younger brother. Was adopted by his stern uncle due to his father's disability, however he and his sister were remarkably close and had a loving relationship, even writing about her, until she eventually eloped from the country with his help. Not much is known about his brother. (and might have had an adoptive brother/cousin later in life but only found one source referencing that, but either way his adoptive family was very cold and abusive). Though Limbus isn't 100% accurate on how much it takes from the real author's life for the character and switches some things around or picks selectively for thematical purposes, but it's neat history + fun to speculate on.
