I am aware of the other Alexander Blair in the area (St. Lawrence Co.), but have full confidence in the Alex I am working spent all of his life after 1856 in and around Depeyster and Heuvelton, NY. I am also comfortable his first wife was Susan Hydorn, Daughter of Peter James Heydorn/Hydorn and Deborah Elizabeth Tryon from several sources. It appears that Peter James Heydorn may have departed the area and left the family farm to Susan, Alexander married Susan and became immediately the owner of a prospering farm in Depeyster. I am not well organized, but scattered here and there among more than a half dozen old hard disks and reams of paper in boxes, most of the story after arrival in this country is laid out. The problem I have is tracking Alexander back through Canada (probably Canada East) to Ireland where odds say he was born in Ulster (Proddy). There is a dirth of free research material coming out of the old country, and considering the turmoil in that area for over 100 years of insurrection, warfare, misrule, and famine, the poor quality of the material is not surprising. I really have to get to work on what I have and get some consolidation done so it all makes sense. Ill health for a number of years between 2005 and early 2016 discouraged efforts that should have been taken then. Charlie
