My ggrandmother Christina Main showing in the 1871 census living at 105 high street edinburgh, dob 1868 her brother Jonathan is also there, father Charles Main born 1838, mother Christina Main born 1849.
Yet in the 1881 census at the same address, Charles was born 1868, Christina's mother is Isabella??????? I know Isabella and Charles were married (the date escapes me) Christina's mother on her birth certificate is Isabella. So who is Christina?????? and why is Charles dob different?????
