Sorry for delay in replying. I am afraid I cannot see any connection with my branch of the Bensted's at the moment, although the name Amelia crops up in my tree too. I am wondering whether Annie's father, Joseph, could possibly have been a brother of my great great grandfather, John (b.Abt. 1808). I only know that John's father was called Thomas. I do not know his mother's name. Joseph's children, including Annie Amelia, would have been born about the same time as John's. I have not yet discovered any of John's siblings - so it is always a possibility.
I'll keep your email for future reference - just in case!
Hope you are lucky with your research.
