Carolyn, I can not give you a marriage date, but I do have some questions.  Some of the data just does not add up. William Dennis served in the 13th Regiment of the Albany County Militia.  Governor Clinton called the 13th Regiment out immediately following the Battle of Freeman's Farm, (i.e., the first installment of the Battle of Saratoga) which was fought on September 19, 1777.  The 13th Regiment fought at the Battle of Bemis Heights (i.e. the second day of the Battle of Saratoga.) on October 7,1777.  William Dennis did not apply for a Rev. War Pension and I have not yet checked Virgil White's Rev. War Service Records for him.  Since he served in the 13th Regiment of the Albany County Militia that means that he was a resident of the Saratoga Tax District some time during the Rev War. William Dennis was the son of a 1779 Saratoga District Tax payer, i.e. his father, Thomas Dennis. Although, I have not yet found Thomas Dennis' lease, based on the common practices among the Saratoga Patent proprietors, I suspect that the Dennis family had been in living in the Saratoga Tax District for more than five years.  The genealogical data that you sent me some years ago indicates that Thomas and Hannah Dennis had four children born in the Saratoga District in 1773, 1775 and 1778.  (you did not give me a date of birth for the fourth child.)  You also said that Patience Dennis was born in Dartmouth, MA on December 11, 1771.  Which leads me to conclude that Thomas and Hannah Dennis probably moved to the Saratoga Patent in the spring of 1772.  William would have been fifteen years of age at the time.  So presumably he was still living under his parents' roof and came to the Saratoga Patent with them.  Since Hannah was not read out of Saratoga/Easton Meeting until 9th day of the 9th month 1779, I assume that prior to that she and the members of the family were in good standing with the Religious Society of Friend.  So what is a 19 year old William doing in New Bedford, MA where Sarah Jane was born? Did he have extended family with whom he might have lived instead of moving to the Patent with his parents? Who is supposed to be the mother of Sarah Jane, who was born in New Bedford, MA in 1776?  Do you believe Sarah Jane's mother to be Elizabeth Sherman or the theoretical, as yet unnamed first wife? I am just puzzled.  Any clarification would be helpful. Sincerely, Leslie
