Hi,
Patrick calls himself McGregor in the Callander parish register, which is on Scotland's People. I must admit, I have mostly relied on the register transcript from Clan Gregor, which I have found to be very accurate. However, I do have a copy of this entry;
21/03/1731 PATRICK DRUMMOND/JANET MCARTHUR JOHN 336/10 65 Callander
Which says;
Patrick Drummond alias McGregor and Janet Mcarthur
I bought it to check it said Janet and not Nansy/Agnes/Anne. It does, but the location suggests it is the same couple.
This is the transcript from Clan Gregor;
1728 Patrick + Nansy McKertr [Braelenny/Wester Brackland] [Callander]
1729 Patrick/Agnis MckArthur Janet Brea of Leny Callander
1731 Patrick Drummond alias McGregor/Janet McArthur John Bracklain Callander
1736 Patrick Drummond/Agnes McArthur Donald Wester Brackland Callander
1738 Patrick Drummond alias McGregor /Anne McArthur James Lurgvuy Callander
1740 Patrick/Agnes McArthur Janet Lurg Callander
1742 Patrick Drummond alias McGregor /Anne McArthur Patrick Cullintogle Callander
1745 Patrick Drummond alias McGregor/Anne McArthur Anne Kirktown of Callander Callander
1748 Patrick Drummond alias McGregor/Anne McArthur Patrick Kirktown Callander
There is also this, which is on Scotland's People, but not in the transcript;
08/07/1733 PATRICK DRUMMOND/ANNA MCARTHUR MARGARET 336/10 72 Callander
I've not bought it, so I don't know if it's related or not.
So, this Patrick was a McGregor who used the alias Drummond, and he used both in the register. The only child I think I know about is John baptised 1731. I think this is his grave;
Kincardine Norrieston graveyard: 115-Alexr MacGregor imo w Janet 23.9.1798 33, fa John McGregor 11.12.1809 79, mo Ann Wood 11.4.1810 80
This John and Ann lived at Coilantogle, like Patrick, which may be a coincidence, but I think he was probably Patrick's son, given the location, the dates, and the names of John's children. I think most of his sons lived in New York state. Alexander, mentioned on their grave, was a banker in Liverpool and Manchester. There is a History of Saratoga County, 1878, which details the family, and links it to John and Ann Wood. The graves of the New York family are also on Find a Grave, and they are on the New York census. So, most of their sons are well documented, and I can post more details and links if you want. The exception is John and Ann Wood's son Patrick, who I think married Margaret Strang, lived in Aberfoyle, and had a son John who was a foxhunter. But this is my speculation, based on the parish registers, and is not as definitive proof as the contemporary history written about his brothers.
On the internet the parents of John, husband of Ann Wood, are given as;
15/02/1730 GEORGE DRUMMOND/MARGT. MCFARLANE JOHN Kincardine
This could be true, and I can post the whole of George's family, but as far as I can tell this family are true Drummonds, not McGregors. The only link appears to be the date, and the fact John sometimes used a Drummond alias. John and Ann Wood definitely lived at Coilantogle, but moved to Thornhill after 1772. The 1878 Saratoga history says they live in Thornhill, and they are buried there. I suspect this is why they have been linked to a Kincardine Drummond family by researchers, but I think the link to Patrick McGregor of Coilantogle is far more likely.
What does Ancestry say about this family, and do you want me to post more information about what I have?
John.
