I, too, am stuck at Jesse Silcott and Jane Samuels.Many years ago I spoke with some Silcott researchers who said that a large annual Silcott reunion was often held at the original home of Jesse Silcott in Loudoun Co. (I just checked a Silcott Forum message, and it looks like the reunion was held in Tahoe Lake, Ca. this year).Anyway, perhaps we could contact one of the reunion organizers to try to find someone who can help.
On the Alder side, I am also descended from James Latimore ("Latimer") Alder and his wife Catherine Silcott. Their son Anderson Alder is my 2nd great-grandfather.From which of Latimer and Catherine's 9 children are you descended? Their children were: Emily Jane (Alder) Thrasher, Ann E. (Alder) McKelvey, Perry Alder, Conrad Bitzer Alder, Anderson Alder, William Silcott Alder, Leonidas Silcott Alder ("Sr." - never married - brother Anderson had son with identical name.), Charlotte Silcott (Alder) Price, Mary Catherine (Alder) Howell.
My research stops at George Alder who died 28 Aug 1737 in Prince George Co., Maryland.I know nothing about his ancestry.I have a copy of his estate settlement after he died, and he was a tobacco farmer with slaves.He married Elizabeth Keech on 16 Dec 1729, and they had 4 children. She remarried to a Joseph Green Simpson, according to a book I read.
I have found the Alder name to be spelled in various ways in the early records: Alder, Allder, Aulder, Ahlder, Older, Elder, and even Allden.This was sometimes the mistake of the person recording the information.I don't know for sure the origin of the name, but some of the early names sound a bit German:Aulder, Conrad Bitzer Alder, Marcus Alder, etc.
Other related families are: Wynn, Silcott, Samuels, Latimer, Robey, Keech, Smallwood, Colthurst, and Evans.
