Russell family Gloryford Ireland

The only place I can find named Gloryford is a village in Derrywode townland in Templetogher civil parish in County Galway - see c1840 OSI map. The Civil Registration district would have been Glennamaddy, however search of births for the surname Russell in this district between 1864 and 1875 is not showing any results..

Do you have any other details that might help your search - names of Mary's parents, details of siblings, did she marry in Ireland ?
Could her birth have been in another location, or a house/estate in another part of Ireland named Gloryford ?

I looked through the registers for all 21 Mary Russell civil birth registrations for 1867 in Ireland - no sign though of any to the parents names you have. There were two records with errors, one I suspect is an incorrect date, the other was a birth registered in Ballymena district, which is showing the incorrect image - will check this further... there was also one cancelled birth, where the registrar had deleted the entry,

There was one Thomas as father, no middle name, a carpenter in Ardigan Downpatrick, his wife's name was Jemima Bennet. None of the mothers for these births had the surname Thompson, and there was no mention of Gloryford or similar...

What was the source of the location and date of birth you have for Mary ?
Were there any other location details mentioned in this for Mary or Gloryford ?

Ages and dates given on secondary sources like death certs etc are quite often inaccurate which would mean a much wider search would have be carried out.. meaning checking many more births for details of place or birth, parents etc than the 20 I just looked at. Other possibilities are that Mary's birth was registered without a first name, or not registered at all, or given the suggested ages of her parents maybe just registered with her mother's surname if Thomas & Mary snr. were not married..

There are a number of Public Trees on Ancestry which match the details mentioned for Mary, these appear to have been copied from each other, but as far as I can see none include any sources for the Irish or England/Scotland records.Maybe some of the owners of these trees have details on paper which they have not included ?
