Explanation:

- Let's break down the family relationships:

- G is L’s maternal grandfather, meaning G's daughter is L's mother.

- L is the only son of F, who is the spouse (likely daughter) of G.

- J is the paternal uncle of M and also the son of I.

- H, sister of J, is therefore M's aunt.

- K is L's aunt by marriage (daughter-in-law of G), making J her husband.

- M is K’s only daughter, making L and M cousins.

- M is related to L as a Cousin Sister.
