Welcome to Ireland Reaching Out!
Roots Ireland has the Drumhome Church of Ireland records going back to the 1700s. Burial records are also available. You may want to consider a short-term subscription to Roots to view available family records. I was unable to find a baptismal record for the 1760 Thomas or his marriage record to Mary McKee.
You also may also want to add the stories of any ancestors who left Ireland to our XO Chronicles site https://www.irelandxo.com/ireland-xo/history-and-genealogy/ancestor-data... Possibly someone will recognize your family.
