Welcome to Ireland Reaching Out!
I checked on Roots Ireland and did not locate a baptismal record for Eleanor with father James. The records for the RC parish of Kilvine do not start until 1870 so if she was baptized in that parish then no record would be available.
I checked the Tithe and Griffiths records for Kilvine civil parish and did not locate any Garry records.
We have an XO Chronicles site https://www.irelandxo.com/ireland-xo/history-and-genealogy/ancestor-data... where you can post a story about Eleanor.
You also may want to consider autosomal DNA testing.
