I have been researching the Corvin's of Wythe Co. for many years now. I've been able to go back 9 generation to abt.1720 and have hit a brick wall. I believe they were org. called Colvin. Mr. Colvin and his wife Susannah Gale had one son John who married Elizabeth Kriger (Creager) had 5 sons and 2 dau. all stayed in Wythe Co. Va. and took the spelling of CORVIN except 2 who branched out to Tn. and Al. who used the spelling of COLVIN.
