I have no idea whether you will see this response after such a long time since your original request in 2002.
My great grandfather was also Hugh Townsend. My grandmother was his daughter Eliza Stuart - born a year before his wife Sarah Larmour died and he presumably moved to Scotland. My grandmothers' siblings were Anne, Alexander, William Edgar and James. Hugh Townsley went on to marry Elizabeth Milliken (formerly McFerran). I have a 'photo of Hugh and his wife and children taken at the farm in 1895. Eliza Stuart went on to marry 3 times on the death of subsequent husbands and became Eliza Stuart Young. Her daughter Whilemina is my mother and is still alive and well.
If you have a sister called Morag I believe I may have met you in Scotland many many years ago when I was a small boy.
If you ever pick this up I would love to hear from you.
