I see this is an old thread.
Children appear to have been Mary, Agnes, Elizabeth, Jane, Sarah, Helen
There are Roman Catholic baptism records for Mary 1834, Jane 1843, and Sarah 1847 (all Glasgow) available from Scotlands People. What names are given for sponsors?
Mothers name varies ORR / AULD / AULT
The 1871 census gives more detail about the place of birth in Ireland for Michael McCormick.
I assume you have this? Please post ALL information.
I assume you have Marys death certificate (1866) and know that her parents were John AULD and Catherine McMILLAN. What other information is included?
