Mary Morris (Reilly) - Birth Cert and Parents

So far I’m fairly certain I have Mary’s marriage and death cert. from this I know she was born between 24 feb 1879 to 23 feb 1880 ( based on being 70 at death in 1950) or 25 nov 1879 and 24 nov 1880 (based on being 39 at her wedding in 1919). If these ages are correct she was born between 25 nov 1879 and 23 feb 1880. This would make her 22 in 1901 census and 32 in 1911 census. From her marriage cert her fathers name was james, a labourer and she was living in Curragh which is also where she died.

I had thought I was onto her when I found this Mary Reilly born to james and Maria in fair green 1881 but this age doesn’t quite match and at 17 in 1901 census she is still living at home.

In the 1901 census in Curragh there is a 54yo James (Labourer) and 50yo Ellen Reilly living in Curragh both were born in Co Cavan. By the 1911 census it looks like James has died and Ellen moved back to Cavan.

However the 1911 census shows Ellen has a daughter Mary Kate 25yo living with her in 1911, would you really have a daughter Mary then a Mary Kate 7 years later? Both Mary Kate and her bro James are listed as being born in Cavan.

Just found Mary’s birth cert! Born in feegat, Meath to james and Ellen (McCabe) who married in Cavan!
