I had done some work on this quite a while ago, and managed to find my X2 grandfather, Samuel Stevenson, born in Cheshire in 1829/1830. I also found his father and grandfather, Ambrose and Ralph Stevenson.
More recently I found a link to rootschat- re: Stevenson- Brooke- Done connection.
It appears that a Ralph Stevenson inherited quite a lot of money from his aunt, Sarah Brooke-Done, needless to say there certainly wasn't anything left by the time it came to me!!- Sarah's sister was Susannah Stevenson, nee Brooke.
I was looking at some photos today with my mother, & came accross a photo that I have seen before many, many times. I asked my mother who it was, she said it was someone from my grandad's family (Stevenson). The guy in the photo was obviously 'well to do', & this is what has raised my curiosity!
