not blood related.
in-law related

Found that he and I are also related.. on both his mother and father's side.. Both sides of his family and mine share initial earlier folk.. so he's a cousin to me/mine lot on and from both sides, closer kin on is fathers side..

20th cousin here, through common ancestors William III, count of Holland and Jeanne de Valois, Countess of Hainault.
