This line is not necessarily connected to the Robson family tree however in 1851, his son is living next door to Robert Robson (who is an ancestor). I was curious to whether the two people were related in anyway but as of yet have found no evidence to support this theory.

Suspected to be a relation of Robert Robson... Interestingly in 1851 census he is living next door to Robert Robson and Mary Oxx. It is possible he married ANN FORSTER 30 APR 1843 Middlesbrough, Yorkshire, England. If this is the case his father is Solomon Robson. It may have been Ann Bell he married on 20 FEB 1842 All Saints, Newcastle Upon Tyne, Northumberland, England. If this is the case is father is Joseph Robson. The conclusion drawn is that his wife was Ann Forster/Foster as son Robert takes Foster as a middle name.
