Becky, It needs to be line from a Davenport male to a Davenport male. You said your grandmother was a Davenport and you may have a brother to test. --------- The following will work OK for Y-DNA: If your grandmother was born with the Davenport name then the male Davenport descendants of her brothers are OK for testing. If your grandmother married a Davenport then any of their male Davenport descendants are OK. The following will not work: If your (and your 3 brother's) father is not a Davenport. If your mother is a Davenport (and not your father). --------- In other words for your brother to be tested he should be a Davenport and your father should be a Davenport. If they don't qualify then you may have cousins that do. Bill Davenport [email protected]
