I have some interesting info that I have spent over a year gathering. Thought it might be of interest to any Greentree decendants:
The Greentree family seems to have started out with John Greentree, who is listed as a landowner in Murderkill Hundred, Kent County, Delaware, in 1726. There is an Isabella Greentree who left records in St. Mary's County, MD in 1738-1748. All the US Greentree's can be traced back to Delaware, and this John, whose widow was most likely Isabella. The next generation is sketchy, as it seems to comprise of a son, William, and a daughter, Isabella. William is listed in Talbot Co., MD records in 1761. Wife seems to maybe be a Mary Dobson. Their children, at least, left better records:Matthew, Alexander, Isaac, and Robert. The well-documented Benjamin is most surely a son of Isabella, Williams's sister, who seems to have gotten pregnant out of wedlock and sent back to England to have her child. She returned to the states in 1762 on a convict ship, Neptune. She lived in Kent Co., DE the rest of her life, which wasn't very long. She died there in 1768. Benjamin was adopted by James and Mary Marshal.
All of William's 4 boys fought in the Revolution, as well as Benjamin. Matthew, b. 1755, was a member of the Delaware Flying Camp. He was a minister, and married (someone?), and had a son, James. Second, he married Susannah Kinnemont Hartley, and third he married Eliza B. Henning. Susannah and Eliza were both widows themselves, and maybe because he was a minister, they both ran boarding houses for young ladies.
Alexander was enlisted in the Chester Co., PA Militia in 1776, but left after 6 months to be a gunmaker. He married Margaret (?) in Dover, Kent Co., DE. Then the family moved to NJ, and then to Fayette Co., PA. His children were:
William (unmarried), Mary (married Emer Bates), Matthew (married Hannah Welsh, Sarah Moore), Sarah (married Rosell Aldridge), Richard (married Mary "Polly" McGowan), Margaret (married Thomas Lakin), Susannah (married Benjamin Thrasher). Alexander died somewhere between 1800-08, and the family turned up in Adams Co., OH, with Matthew listed as head of household.
Robert was in Kent Co., DE in 1774, in MD in 1790, and then in Greene Co., TN land grants. His line would be picked up in TN.
Isaac was keeper of the Ferry from Rock Hall to Annapolis in 1775. Before that, he kept tavern at the Talbot Courthouse. In 1776, he was extensively documented as being an express courier, carrying important documents during the war. Some time in 1777 he dropped out of sight, and it is certainly likely that he was killed while serving his country.
This has been a very interesting hobby for me and a fellow genealogist that I have been working with. If anyone has their Greentree line traced back sufficiently enough that we can tie it to this original family, please share with us. Maybe by the time I am 90, I will have this family searched out and documented well enough to publish, since it seems that no one has yet pubished a book on the Greentree's.
