Tracing the above family and interested in information about David Gregg born in Yorkshire(?) in 1826 ,died in Australia (Tasmania) in 1917 and was married to a Margaret Connelly (this may have been Kinelly) from Ireland.
Wow - three years since your post! While I don't have your ancestor, it is possible I have one who is related. I have the Rev. Tresham Dames Gregg who was born about 1800 in Mt. Jerome, Ireland, but who married a Sarah Pearson of London, England. They were married in Yorkshire, England and may have lived there for a time. So let me know if this may be a connection for you!
