Birth certificate

Ronr,

I have checked the Civil Records online. No record for a Susa/Susana Nestor in Ennistymon 1893.

Subscription Site  www.rootsireland.ie has a record of a Susana Nestor having been baptised in Kilshanny on June 25 1893.  Parents: Connor Nestor and Maria Crimmins. Address: Carhuduff (Carrowduff).

You can access this record for free at catholicparishregisters@nli.ie  (National Library).

You could also contact the Civil Record Office in Ennis  Tel 353656868048 - 35365683-049 to check for the record on the Ennistymon register. Civil Records in Ireland are from January 1st 1864.

Regards,

Ronr,  there are two births for Susan Nestor. you would need the mothers maiden name to check.
