My next door neighbour loved my DD1's middle name and just asked if I minded if she used it for her DD2. I was fine with it - I see them just about every day, the girls are all in CC together so I think we are closer than cousins in terms of the amount of contact the girls have. Funnily enough I don't see her DD2 as having the same middle name as my DD1 - they are individuals so give a different spin to the name if that makes sense
