There's a dna match to my dad of 10.7% (759.4 cM) on his father's side.
Dad also has another match on his father's side of 14.3% (1,015.9 cM).
This second match, also matches to the first person, but on their mother's side at 4.5% (335.4 cm)
I'm confused as to the relationships going on. Would appreciate someone else's opinion.
