Searching for Ancestors of Mary Ellen Alexander, Nee Byrne

Hello

My grandmother, Mary Ellen Byrne, was born in 1897 in Castlefinn, Country Donegal. She was a servant in "The Grove" Manor House, when she met my grandfather, William Alexander.

Her mother was Eliza McElhinney, and her father was William Byrne.

I am looking for any information on anyrelatives that might still be living in Ireland or otherwise.

Any help would be appreciated.

Thank you

Deborah Alexander
