it's been so long since I have done ancestry work since we live far away from the US and Canada! it is exciting to think about it again.

Unfortunately, based on my research, I found that there are two family paths in Nova Scotia, mine that is descended from Alexander Horner who came from Northern Ireland via the British Army and settled in the opposite corner of Nova Scotia from Halifax (I still have Horner cousins in Digby Neck), and the Halifax family that has no connection with my Horners. In fact, I saw quite a few Horners in the Halifax area from the same family.
Where did your first Horner come from? I have all my notes in storage, and so don't remember the details any more.
