Gaffney family

Hi.

I recently contacted you about trying to trace where my husband's ancestors were from in Ireland.   I think there may be a connection with Cavan.  His great grandmother, Isabella Gaffney (McGuire) I think, was born in ireland in  or around 1868 and she married john Gaffney ( born i think in ireland around 1862)..  They married in Glasgow in 1890 and all generations then lived in Scotland.   Isabella's mother was also called Isabella McGuire ( Devlin) and her father was patrick McGuire.   John's father was John Gaffney and his mother was Mary Feeney. 

Any help would be appreciated

Many many thanks

Emma
