I'll recheck these, or at least the 1790 one which I don't remember seeing. The lot that our Alex received was 15 W 1/2 in 2nd Cons. SSRR in 1802.
When I was looking at petitions for Alex and/or Donald Grant, I came across one for a Richard (not our line) which said that at the time (1815), there were FOUR Alex'r Grants in Charlottenburgh. No wonder I'm having a problem-- especially since this Alex seems to have once been Donald.
Any chance there was a Marjory Grant on the Pearl?
