Hey, I'm Trenton Lance Niblett and I've come to the conclusion that your great grandfather is William Monroe Niblett. His father was supposively James H. Niblett. William Monroe married Sarah Jane Lynch. William Monroe's father was John Niblett, who married Mary Ann Hopkins and he was born in Avening,Gloucester, England. John's father was Richard Niblett who was born in the same town in 1756.He married Mary Franklin. This is all that I have for right now. Please, if you have any info. let me know or if you conclude that any of this is not correct, let me know that also. Thank you very much.
