In doing research on the Poplett family history, I came across an Isaac Allen (1755-1831) who died at age of 76.I wonder if he could be an ancestor of your Isaac Allen.The following is what I know: He was married to Margaret Poplett, following the death of his first wife, Frances Pettit.I though that Margaret might in fact be Margaret Elizabeth Poplett, because the only Poplett records I could find of a Poplett in the United States at that time was an Elizabeth Poplett who came to Virginia as an indentured servant in 1774 at the age of 28.From there, she likely ended up in North Carolina, and perhaps later in Indiana or llinois (which was Indiana territory).If this is true, she would have been 9 years older than Isaac, possible since it was his second marriage.Anyway, the KNOWN FACTS about Isaac are: Born:March 15, 1755 in Virginia. Died:December 15, 1831 in Indiana at the age of 76. First Wife:Frances Pettit. Served as a Private in Virginia during the Revolution.
If there is any link, I would like to know. Thanks Richard Poplett
