DH and I are both AH Surname.
DS is SP Surname.
DD is due in OCtober. middle name will be the village where we first lived together (don't worry is also a normal girl's name) - which begins with H.
We can't agree on a first name, but currently under discussion (and not yet veoted after a week) begins with A.
Would DS feel left out or special if he was the only one in the family who is not AH Surname.
(PS I don't need to know about the practicalities of having several people with the same initials in the same household, I grew up with a brother with the same as mine).
