Every time that I review the early Pfaffenhoffen records I find something new. I reviewed the list of baptismal sponsors again today and I located some records that "prove" that Nicolaus Schmidt and his wife, Agnes, were the parents of Catharina Schmidt (1583 - 1622/6). I located five examples (I missed these when I checked for Catharina's mother earlier this year) where Agnëß, wife of Clauß Schmidt or Clauß the Schmidt, was a sponsor:
29 December 1577, p. 199, #40
21 Trinitatus 1587, p. 207, #33
25 August 1588, p. 208, #20
8 October 1592, p. 212, #36
11 March 1592/3, p. 213, #12
Clauß Lohr [der Schmidt] and Agnëß, daughter of "Michelß Hanß" of Kindwiller were married on 26 August 1577. Agneß, wife of Clauß Schmiden was buried on 12/17 May 1596. Clauß Lohr married Barbara, daughter of ?Kunkerhausen of Schalkendorf circa February 1598. This Barbara, wife of Clauß Schmidt, was a baptismal sponsor on 19 February 1597/8. Barbara, widow of Clauß Lohr, married Emrich Schuhmacher, in July 1600.
Additional confirmation that Clauß Lohr and Clauß Schmidt were the same person: Jörg/Georg, son of Clauß Schmidt, was a baptismal sponsor on 9 Novmeber 1595, 16 November 1595, 8 February 1595/6, and on 16 December 1599. This Georg "Lohr" married Gertrudt on 3 November 1600. There is no christening record for this Georg Schmidt/Lohr in Pfaffenhoffen, but he was probably a child from the marriage of Clauß Schmidt and Cleopha, and born prior to their daughter Maria. There was only one child listed for Clauß Lohr, a son Wendling, christened on 13 November 1586.
I located several examples where Walburg/Walpurg Duchmann was a baptismal sponsor. She was listed as Simon Franck's daughter on 1 April 1593, 17 January 1594/5, and 6 July 1595, and she was listed as "J. Walpurg Simon Duchmanß fr." on 12 January 1594/5. So, I am now "convinced" that Simon Duchmann and Simon Franck were the same person.
I also located an example in June 1589 where "J. Ursula, Hanß Jacob Duchmans Dochter" was a sponsor (the surname Duchmann wasn't crystal clear in this example, but it looks like the other entries by this pastor). Information that I have been provided by "professional" German genealogists is that a person couldn't be a baptismal sponsor until they were confirmed (circa age 14). I have several documented examples where children of the age of thirteen were sponsors. So this Ursula Duchmann must have been born no later than 1577. This would predate the marriage of Johann Jacob Duchmann and Apollonia Gams in 1585. Have you located any other records that suggest that this Johann Jacob Duchmann was previously married?
There was some discussion that Nicolaus Diemer (ca. 1624 - 1704) was the son of Wendel Diemer. Nicolaus, son of Wendel Diemer and Barbel/Barbara was christened on 11 December 1625 in Pfaffenhoffen. I abstracted christening records for one child of Wendel Diemer and Agnes (Margret, 1621) and four children of Wendel Diemer and Barbel/Barbara: Nicolaus (1625), Linhart (1627), Friederich (1629), and Margreth (1631/2). I didn't find a marriage record for Wendel Diemer and either Agnes or Barbel/Barbara, a death record for Agnes from 1621-1625, or a death record for Wendel Diemer and Barbel/Barbara through 1650 in Pfaffenhoffen. I did locate Wendell Diemer [Linharts Peters Sohn] as a baptimal sponsor in February 1612/3 and I located the christening record of Wendling, son of "Leonhardts Peter" on 26 October 1589. Nicolaus Diemer did have children named Peter and Margaretha, but no sons or grandsons that I have located named Wendel or Wendling. Have you reached any conclusions on this family?
