Re: HOAG - name change to PRENTISS

I am being blown away - I work at Colonial Williamsburg and the extended family I research is the Geddy - one of James Geddy's sons is William Waddill Geddy and marries an Elizabeth Prentiss from Londen, Ireland (so say the records at the cemetary- but we think that means Londonderry)b. abt 1777 and d. 8 Mar 1849 in Dinwiddie Co., VA; buried at Blandford Cemetary.Could this be the same Hogg/Hoag family ???Any info would be appreciated.
