The British census returns usually state just IRELAND, but I have now got evidence of Catherine Sheridan b.1841 from Cavan County.(died 1907 South Shields). We know she had a sister Ann b.1825 and possibly a brother James b.1836. All three had gone over to live in Willington, Co.Durham U.K. Catherine was married(?when)to a PETER LAMB.1831-1884. With this new lead I wondered if anyone researching the SHERIDAN family name has come across these people? Thanks to the person who has given the address of the County Cavan Genealogical Research centre. That might be very useful to chase up a marriage (R.C.) for Peter and Catherine who were my husband's great grandparents.
