I have found a Daniel Bossert and Eleanora Hall proclaimed marriage Feb 5, 1788 in Frederick Co MD Lutheran Marriage and Burials 1773-1811 wit: to this marriage were Johannes and Elizabeth and Catharina Bossert, John & Eli Hall.You may already have all of this information.I have a Daniel Bossard or Bussard or Buzzard however you want to spell it in the same County he was born March 14, 1736 in Alsace Lorraine Germany.This Daniel had Children Elizabeth, Johannes, Catherine and Daniel as well as several others including Judith from whom I descend.This son Daniel was born Dec 12, 1771 in Frederick Co MD . The parents of this son Daniel are Daniel and Sophia Renner Bossard.There is a good chance this is your Daniel.They were from Stony Lick Farm on Mink Farm Road ( same Mt. as Camp David) the old house still stands and some of the graves are there.They have added on to the house but you can see the original part. We don't know where Daniel Sr is buried but his wife Sophia is in the Glade Cemetery as she died later and had moved to town she died in Feb so the weather was probably to bad to take her back up the Mt. for burial. Most of those in the old family cemetery are the Oldest son Peter's family.contact me by e-mail for more info.
