There are a few pedigree files at familysearch.org which have Catherine married to both Thomas Stone and John Finnell. Be aware, that information is unsourced. I.e., there is no indication of records or documents supporting the information.
Also note, those files have her birthdate anywhere from 1765 to 1780 - again, no source information.
FYI - there is a marriage record for a Catherine Surry to John Finnell.
