Seeking source of WRONG information. Numerous trees on Ancestry.com, other genealogy sites including LDS all have identical wrong info. Family migrated from VA to Mason County KY around 1805.

Somehow, somewhere 95% of info on one son of Isaiah McGraw b 1770 Fauquier VA and Ann Norris b 1779 MD is WRONG. Keep finding trees, etc showing son Isaiah married to Sarah A. Collins. Correct info is son Hiram b abt. 1805 KY or VA married Sarah Ann Collins 8Jun1839 [per Mason County KY Marriage Records 1804-60 Vol II-VI]. Also Civil War documents of Hiram's son Anthony state Anthony's parents are Hiram McGraw and Sarah Ann Collins. Cannot figure out where error is. Don't know if original document is wrong (i.e. Hiram had brother named Isaiah; perhaps brother Isaiah/father Isaiah was witness & names got written on wrong line) or if there was a transcribing error somewhere and it's just snowballed.

How to I find source? Once found, how do I correct? This is driving me nuts & is big roadblock, especially if I want to join/apply at a historical society or DAR. Causing me to question my research. I know I'm in right church; maybe wrong pew?

Can anyone offer advice? I live in New England; can't get to Mason County in person to 'eyeball' records for myself. Will gladly reimburse copy fee/postage etc if someone gets copy of original document(s).

Any help or suggestions appreciated. Thanks.

(Also need place/date for death of Hiram; can't find him after 1840 census.)
