Looking for info on Thomas Rush born 1832-1834. Father Michael Rush Mother Ellen Gibney
Walters:
I searched the subscription site Roots Ireland and the subscription site FindMyPast.ie and did not find any baptismal records for children of a Michael Rush and a wife with the surname Gibney. Likely the baptism of Thomas occurred in a parish which no longer has records back to the 1830s.
The surname Rush in the 19th century was mainly found in counties Mayo/Galway/Roscommon in the West of Ireland and in counties Down/Tyrone and Armagh in Ulster province now Northern Ireland.
If you have not done so already, you may want to consider DNA testing.
