Edward Penny died in 1824 in New York. A brief abstract of his will is as follows:
EDWARD PENNY, Pittstown Wife: Phebe. Oldest son: Benjamin. Son: Ammiel. Oldest dau.: Esther Marvel. Daus.: Thankful Horton, Phebe Carpenter, Hannah Townsend, Rachel Penny. Son: Edward Jr. Grandson: Voleny Marvel. Exec.: son Bangs? Penny, son Edward. Wit.: Abner Thurber, Betsey Thurber, Isaac Townsend. Dates: March 20, 1824, Probate Sept. 22, 1824. Vol. 7, P. 262.
I'm looking for Voleny Marvel. First of all, I'm quite sure his last name is actually Marble, and I've seen this in a few other sources about his name. I don't have a birth date for his mother, Esther, but I do know she was born between 1778 and 1782. What I'm trying to figure out is if I can get an idea of Voleny's birthdate based on the fact that he was included in the will.
Edit: I should have included the actual will, which can be found at FamilySearch. I have included the section with his name, along with my attempt to transcribe, below.
And further I do give conditionally to my Grandson Volney Marvel the sum of One hundred dollars in case my son Edward should decline to give a good & sufficient title of a certain piece of land lying in the town of Charlestown in the County of Montgomery which he my son Edward now has a title for & in such case the said Volney is to pay to my son Edward on the receipt of such Deed the sum of One hundred dollars, then this gift to the said Volney is to be null & void otherwise to be paid out of my real estate after my decease.
