My 2nd great grandmother was Jane Pirie, daughter of James Pirie and Ann Hendry of Marnoch. Jane died a pauper in Forglen in 1905 where she gives her parents. Her age at death is 75, which points to 1830 as the year of her birth. The same birth year is also pointed to in the 1871 and 1861 censuses where she is living with her father James Pirie in Marnoch, and in the 1851 census (as Jean) where she is living with both parents and 5 siblings including her sister Anne (born 1833). She gave birth to my great grandfather in 1851 but didn't marry the father (who scarpered to the U.S. and had a different family there).
She is not in the 1841 census, when she would have been 11, but the younger sister Ann is listed age 9. The surname is misspelled "Perrie" Where is Jane? It's possible that she was just somewhere else when the census taker showed up, but there is a bit more mystery.
I can find a record of birth for all her siblings, but nothing for Jane. There is, however, another Ann, born in Marnoch on 19 December 1829. I know it is fairly common when a child died to give a subsequent child the same name, but I can't find a death record for the 1829 Ann. This is an odd thought, but could Jane and 1829 Ann be the same person? If not, where did Jane come from?
Thanks for any help or advice!
