I'm having trouble tracing William R Carscadden born about 1824 in Coleraine Londonderry, a Linen trader and Laceman who went to live in Leeds and married a Mary Bullivant in 1844 in Leeds They had at least 9 children and at one time were in Sheffield listed on the census as Carr. Every browser I try doesn't usually even recognise the name. Anyone come across the name in Derry?
