I have him born in Westminster London England Feb 1, 1740, death was Jan 1796 in Grainger Tennessee, my moms family all generate from Tennessee so I think I am on the right track. Rachel Oliphant is his wife, they married in Hunterdon NJ 1763, so it is weird how he married here in NJ and died in Tennesse.
I am match DNA with his son my 4th great grandfather Samuel West born October 24, 1767 in Grainger County Tennessee and died there in 1834. He married Elizabeth Thompson another DNA match, she was born 1781 in Virginia and died July 1850 in Grainger county Tennesse,. Rachel Oliphants dad, Ephraim another DNA match was born in Staten Island NY and died in VA., his wife Sarah Stout's family has very strong family history in Monmouth County NJ where I grew up which is unny, she was born 1725 in Clover Hill NJ and died July 10, 1768 in Kingswood Va.
hope this is helpful, I am new to spreading out from Ancestry to get my answers.
