This is all speculation. Frank and Rosa would have been born about 1845 to 1865? They were from Kentucky? There were many immigrants to kentucky from Maryland from 1790 to 1820's.Some of those immigrants were Catholic.THere were (and are) many Adams families in Southern Maryland, specifically St Mary's County. Rosa was a common name among my Catholic ancestors from St Mary's County in the 1830 to 1845 era. So might your Adams ancestors trace back to SMC?Try posting to a Kentucky County list at Gen connent "IF" you know the Kentucky county they were from.And post to the St mary's county MDSTMARYS-L at rootsweb. Or Genconnect. Hope this helps.
