I am searching for any information about my great-great-grandfather Thomas A. Salkeld, who emigrated to the US in May of 1852 at age 22. He shows up on the 1870 US Census living in Ohio, occupation coal miner, married to Ellen ?, age 32, who emigrated about 1848 from England. There are 5 children shown on the 1870 census as well as a Robert Salkeld, age 31, born in England, occupation Boilermaker. The relationship between Thomas and Robert is unknown.
Later the Thomas Salkeld family moved to Illinois and had at least two more children. Robert Salkeld moved to Texas, then to California, and had at least three children.
I know nothing about Thomas Salkeld's family in England or where they lived. Any information would be appreciated.
