Pat, your Catherine (or Catharina as I have her listed, was a sister of Johann Jacob (or Jean Jacques Reeb). My information on the date of birth or baptism for Jean Jacques shows his date as 15 March 1744 not 1746 as shown in another post on this forum. I show the same date as you for Catherine/Catharina but I show her marriage on 14 Feb 1774 to Anton Schueht. Could be my record is not exactly correct, I can't say for certain because I did not read the Dauendorf records. It is not in my primary location for research in that region for REEBS. My search was primarily done in the records of what is sometimes called Alsace Bossue by the French or der Krummes Elsass by the Germans and is presently in the very northwestern portion of the French department of Bas-Rhin, in earlier times owned by the Counts of Nassau and known as Grafschaft (countdom) of Saarwerden then later divided by Nassau-Saarbruecken & Nassau-Weilburg.
