Looking at records in the Charlestown Town Council, on 10 Sep 1779, Joshua Kenyon (son of Enoch) is summoned for Grand juror service and that same day Capt. Joshua Kenyon is summoned for the Pettit juror.
On the 1790 Charlestown RI Census there are two Joshua Kenyon's - one with 2 males and 7 females and one with 4 males and 2 females.
The Joshua with 7 females is listed next to Ephraim Burdick & Isaac Saunders.
The Joshua with the 4 males and 2 femails is listed next to Sarah Potter widow (aka Sarah Kenyon) of William Potter decd and George Hall.
On the 1800 Westerly RI Census has a Joshua Kenyon.
On the 1800 Charlestown RI Census there are 2 Joshua Kenyons, one called #2.
Per land deeds - Joshua son of Enoch and Lucy signs deeds with a wife "Elizabeth" in 1783, 1786, 1792, 1802 and 1803 and remains of Charlestown. He also mentions in some deed transactions his siblings Sarah Potter and Roger Kenyon or Lucy as his mother and/or Enoch named as his father.
Per land deeds for the other Joshua who has Mary as his wife, signed in 1792. 1797, 1803. He is called Joshua of Westerly in 1796 & 1803 deeds signed as Joshua and Mary.
This other Joshua Kenyon maybe the son of Jonathan Kenyon & Sarah Rogers of Charlestown as in a 1782 deed, he receives land next to Jonathan Kenyon late deceased from other sons of Jonathan - Benjamin, Samuel and Nathan.
He could also be the son of Jonathan Jr., son of Jonathan Sr late deceased, so that would be that Benjamin, Samuel and Nathan are Joshua's uncles instead of his brothers.
Jonathan Jr. was the eldest son and heir of the Jonathan Sr. & Sarah Rogers and he died in 1766. Jonathan Jr. was born about 1725 ish so he could have a son born in the 1750's who could be a Captain. Per a land deed dated 1767 (after death of Jonathan Sr.) he signs with wife Sarah.
But if the Captain is born 1739 (per Westerly gravestone stating Captain is 64 years old at death in 1803) , then most likely Joshua would be a brother to Jonathan Jr., and Benjamin, Nathan and Samuel.
The will of Joseph Cross shows that he has a son in law Jos. Kenyon. He says her name is Mary Kenyon in that same will.
The marriage of Joshua Kenyon and Mary Cross is 1774, seems late. Joseph maybe had a first wife and Mary is older? He married Abigail in 1746.
So who is up for a challenge of trying to figure out the Joshua's and their respective families and descendants?
