Martha Greathead

Pauline wrote to me as a result of my contacting her through Genes Reunited and told me about her 2xgrt uncle who married Martha Greathead. Great I knew when she married but not to whom. I now also know she had a daughter and I found the family on the 1891 and 1901 census

Since Martha is my 3rd Cousin 3x removed I wonder what relation I am to Pauline?

Thank you Pauline
