I recently made a fascinating discovery... any family tree, website, records I've seen state Alexander Hay's b'day as Aug 1, 1784 baptized on the 5th at Corn Market, Old Meeting Church, Sunderland Eng. A quick internet search reveals the names of his parents, siblings and dates.
Things didnt match up though. Alexanders grave says b.1787, census records estimate to be 1791. An exhausted search found that Alexander Hay b.1784 died when he was 2. Burial at the Holy Trinity in Sunderland. His parents had another child and also named him Alexander. He died at the age of one.
Actual records state that the Alexander and Jane Hay (pre-Canada), some of us are searching for, is infact from Shoreswood, parish of Norham and bounty of Durham, according to actual baptism records of some of his children.
I just thought I'd put this info out there because so many members have the same info and I think it's incorrect. ;)
Hope this helps! The search continues...
