Hi Mymeggirl,
You mention this Thomas Round lived in Cambois, so from that bit of info we must be connected. So many "Round" families lived in Netherton or Dudley back then, but only part of one family moved to Blyth or Cambois in Northumberland.
Thomas was born 7th April 1855 in Cinder bank, Netherton, West Midlands. Thomas's younger brother Mark Noah Thomas Round born in 1868 is my great great grandfather.
In 1877 Thomas married an American lady by the name of Mary Jane Tart in Kates Hill, Dudley. They had lots of children, 8 or 9 from what i can remember.
Thomas and family moved to Cambois in the late 1880's. On the 1881 census he was a slate setter labourer.
Thomas died 4th September 1920.
I worked extensively on the Round family with another connection to the tree so i can not take all the credit for the information we found.
If you would like to pm me with whatever else you would like to know i would be more than happy to help.
