Liam married Maria, fathering Paul (stillborn) and Little Liam (born after his father's death)
Michelle, Paul and Liam's dad Barry is Johnny Connor's
second cousin; Johnny was also a close friend of Carla's mother and the presumed father. Carla's mum only told Rob that Johnny was Carla's father.
This means Carla, unknowingly, married her
third cousin Paul.
That would make Aidan and Little Liam
third cousins once removed.
A hypothetical child of Maria (mother) and Aidan (father) would be Little Liam's
half-sibling as the closest relationship is the one that "counts".
On the other hand, a hypothetical child of
Eva (mother) and Aidan (father) would be Little Liam's
fourth cousin.
Just to compare with another soap - in EE Lexi Pierce is the daughter of Lola Pierce and Ben Mitchell. Lola and Ben are
third cousins once removed, making Lexi a
third cousin twice removed to Ben's half sister Louise.
