I have just joined ancestry.com. My maternal grandmother's grandfather was Michael Forde from Bandon.
My grandmother, Anne Forde, was born in 1883, in Ringaskiddy, Co Cork, so at a guess her grandfather, Michael Forde, was born before 1840 in Bandon.
He may have married a woman calld Ann.
I think my tree is public. It is under Riordan.
Let me know if you see any connection.
