Thank you so much for your replies everyone - have only just seen them so sorry for the delay in replying.
Unfortunately I need to find Bridget's birth or marriage certificates to ascertain what her father's name was and at the moment I haven't found either. There appears to be both Catholic and Church of Ireland families called Sands/Sandes etc. in Cork area and I wouldn't know where to start looking without her father's details.
I believe Bridget was a catholic as all her children were baptised in the catholic church.
She married Francis McQuade but I haven't been able to find a marriage in England, Scotland or Ireland so am a bit stumped.
She had 5 children in South Shields, Jarrow, Co Durham between 1864 and 1876. Whether she had any before that I don't know but no others appear with them in the England 1871 census so presume the marriage was year or two before the birth of Thomas.
Thomas McQuade born 1864 in South Shields. His godparents were Laurence Bradley and Rosanna Donelly. He died in Apr qtr 1865 in South Shields.
Sarah Jane McQuade b 1868. Her godparents were Hugh & Sarah Lavery. She married Thomas Donnelly in Boston, USA and died in Boston in 1949.
Francis McQuade b 1870. His godparents were James Sands and Catherine Cullen. (changed surname to Wade when he joined the Army in 1888- firstly the Durham Light Infantry and then the 6th Inniskilling Dragoons. He married Elizabeth McBride in 1904 in Sunderland (was stationed at The Curragh at the time) and they had two children, one born in Cairo and the other in Mhow India. He died in Mhow in India in 1909.
Joseph McQuade (McQuaid) b 1873 (haven't got baptism for godparents) He married Ellen McManus in 1903 in Sunderland and they had 7 children and died in Sunderland in 1950 (not confirmed)
Patrick McQuade b 1876. His godmother was Mary Ann Hughes. He married Margaret Kirk in 1901 in Sunderland and they had 8 children. He died in 1928 in Sunderland.
So really until I can find a birth/baptism or marriage I can't move forward. The marriage could be anywhere as I'm not sure where Francis McQuade comes from in Ireland.
There was another McQuade family in Jarrow at the time but I haven't found a link to them.
Thank you all.
