You have mixed up two different Carter Bassett Harrisons. In actuality, there were three CBH's. The CBH (2) who was married to Mary Anne Sutherland (1814/1893) was the SON of William Henry Harrison. He was born 10-26-1811, married 6-16-1836, and died 8-12-1839. CBH (1) might have been WHH's brother. And there was a nephew of WHH's also named CBH (3).
Also, some places show CBH (2) and MAS having a daughter named Anna Carter Harrison (1837/unknown) who married a David Waddle McClurg (12-18-1831/unknown). ACH and DWM had a daughter named Anne Harrison McClurg (bd\dd unknown) who married Thornton Fitzhugh (1864/unknown) in 1888. They apparently had a son named James McClung Fitzhugh (bd/dd: unknown) who died unmarried.
From somewhere appeared Anna Harrison Thornton (1835/1-17-1883) who was the daughter of CBH (2)'s sister Mary Symmes Harrison (1-22-1809/unknown) who married a Lee Mason Fitzhugh (1838/unknown) and begat some children together: Thornton Fitzhugh (1864/unknown), George Lee Fitzhugh (1866/1891), Charles Harrison Fitzhugh (1868/1869), Anna Thornton Fitzhugh (1873/unknown unmarried), and Lee Mason Fitzhugh (1876/unknown unmarried).
Whew!!! It sure can get confusing when these prominent families name their kids practically the same names. And even worse when they start marrying their first and second cousins who already have similar names. AHT just popped up on my radar screen when I was trying to give the info I'd found. I had to go back and find out who she was!! Imagine my surprise when I found out that she was CBH (2)'s niece!
BTW, I read an interesting history of the close friendship between the William H. Harrison family and those of the Sutherland, Ramsey, Irwin, and Findlay families. Nancy Ramsey became the 3rd wife of John Sutherland and MAS is their daughter. Mary Ramsey (Nancy's sister) married Archibald Irwin and they parented Elizabeth Irwin who married John Scott Harrison CBH (2)'s brother. Their son, Benjamin Harrison (the kazillionth), became 11th president of the U.S., following in the footsteps of his grandfather, WHH. Their other daughter, Jane Irwin (1804/unknown) also married well in 1824, when she tied the knot with William Henry HARRISON Jr. (1802/1838), another son of our 9th President.
Evidently, the Irwin girls (Nancy's nieces) met the Harrision boys at the Sutherland's home in North Bend, OH, and went off happily into the sunset and history.
The story that I read was very informative since it finally gave me the info that Nancy Ramsey and John Sutherland were MAS's parents. And I found all about the Irwin and Findlay familes as well as the Ramseys. It's amazing to be able to tie some threads together just by reading everything that I can. I've been looking for the parents of MAS for over three years. And this chance reading of an unfamiliar web site was a treasure trove. I'm not really sure whether it is a compilation or from one source. I just found it yesterday and am planning on contacting the web site owner.
Anyway, hope you've enjoyed this! If anyone has anymore about MAS and CBH (2) to share, please let me know at firstname.lastname@example.org
