Hi Sandra,
Just saw your message now! I see William, born 1833, his descendents have been put onto rootsweb.com by a Jane Neill. (I'd love more info!) She does not include another brother, Philip, born 1842, my gg grandfather. He ended up in Manitoba, Canada (where I grew up). I would love to share what I know, but would like to email you personally! I am particularly intrigued by a mention in an old newspaper of him going to visit a sister in Australia. Any thoughts?
