Hi Brian I found these Errigal Parish Register entries. Looks like your family. No addresses given unfortunately, but you could look up the Civil Registrations of the births to get more info.: 29th June 1873 Daniel O’Kane and Catherine Mullan had a daughter Margaret baptised. Denis O’Kane and Catherine O’Kane were sponsors, Errigal. 31st October 1878 Daniel O’Kane and Kate Mullin had a son Daniel baptised. John Mullan and Mary Mullan were sponsors.
