McDevitt/McNelis family Glenties/Letterkenny/Ramelton

Hi, I began researching my family history and would love to know what relatives I have in Donegal. My great-grandmother was Delia McNelis b in Glenties 2/6/1867.

Delia's parents were Timothy McNelis (b Sept 1834 or 37) and Mary Gallagher (b 1841) of Glenties who were married there on 2/27/1865. They immigrated to the US around 1870 ending in Loda, Illinois, and had 10 children total. 

Delia's maternal grandparents were Daniel Gallagher who may have lived in Ramelton and Nora Sweeney. Her paternal grandfather was Patrick McNelis.

Delia married James Henry McDevitt who was born in the US; his father was John Patrick McDevitt born 1829 in Letterkenny and may have lived in Ramelton.
