Johann Gulder, a priest (Priester [sic]), his wife Anna Margaretha, and daughters (Anna Maria, age 7; Christina, age 2-months) are recorded on the 1767 census of Pfeifer in Household No. 1 with a note that Johann Gulder is serving as the colony's mayor (Vorsteher).
The orphan Johann Adam Roth (age 14), son of the deceased Johann Georg Roth, is also recorded on the 1767 census of Pfeifer along with the Gulder family. The 1767 census does not record a relationship between the Roth and Gulder families. They had settled in Pfeifer on 20 August 1767.
The 1767 census records that Johann Gulder came from the German village of Neuburg am Wald in the Mainz region.
There are no known surviving male lines of this family among the Volga German colonies.
