George Archer is the correct answer to the first Archer in Virginia. Richard Archer is not proved, possibly entirely fiction. I've found the same records as you have done. Thank you.
Lineage Societies as references.
Many of my ancestors here at wikitree are found in XVII Century Colonial Dames, Daughters of the American Revolution, Sons' of the American Revolution, &c. I'm not a member of any of these organisations, but I adhere to their mission to respectfully represent their ancestors histories, Ancestry.com is too frequently found here as sources devoid of any facts. The more devoid of facts, it seems, the greater the number of family-trees that are referenced as sources. It is quite depressing at times to find knowledge corrupted in so thoughtless a manner. Respectfully Yours, Chas Vigneron
