Virginia...watching replies to your query...I don't have the Union Cemetery book only the New Jerusalem which is the OLD cemetery behind the church but I checked in that and found nothing on either Younkin or Firestone. I did find the following in the St. James United Church of Christ Church Register of Loudoun County, VA translated from German to English by Jerry and Tedi Jeen Mower: Pg. 12: George born 10 October 1793; bap. 26 Dec 1793; parents: Johann Juncken; godparents: Jacob Adams and wife. Pg. 23: Rudolph Junckin and w/Elisabeth parents of Samuel b. 2 Sep 1798; bap. 31 Mar 1799; Wit: John Junkin and w/Chatharina. Don't know if any of this help...good luck! Looks like you got a lot of response! Shelvy
