The following info is from the Maryland State Archives, from the Frederick Co website
ADAMS - Frederick GRAMMER of Annapolis vs the heirs of Vale ntine ADAMS - Petition to Sell Valentine ADAMS of Frederic k County, d/ c1790 intestate widow - Margaret and 7 childre n - ...George in Kentucky ...Andrew ...Abraham ...Mary w/o John SPANGLER ...Margaret w/o Abraham ALLBAUGH ...Casper (a minor) ...Peter, dec (d/ c1785) & his children - ..........Peter and Rebecca, minors
We agree on Peter, George, Abraham and Margaret.
Casper is on this list, but no baptism, and not on your list.
Andrew is on this list, and also in court papers for George George "...Owned tract Rattle Snake Spring, 255 acres, pt Monocacy Manor...He was asked if in the Fall of 1792, if he sent to Kentucky by his brothers, several negroes...He responded he hadn't, it was his brother Andrew". This is clear that George in Kentucku in 1792 had a brother Andrew, and Valentine's papers show a son George in Kentucky in 1792, and another son Andrew.
Where does the info for John come from? He is not in the Evangelical Reformed Church register. Could this be the same person as Andrew?
Is Mary the same as Maria Magdalena b 14 Jan 1763? Mary Adams m John Spangler 20 Dec 1788.
How much info do you have on Valentine's father Martin, as well as his siblings?
I'm 99% sure my Andrew J. Adams b 1781 was from this family, just can't prove his parents yet.
