Johann Adolph Manweiler, son of Hans Manweiler, was baptized 5 August 1703 in Finkenbach-Gersweiler, in the Pfalz (today Rheinland-Palatinate), northwest of Mannheim. He married on 25 April 1726 in nearby Meisenheim to Maria Elisabeth Schliechel. Among their children are (all baptized in Meisenheim): Philipp (baptized 17 August 1732), Johann Adam (baptized 5 July 1743), and Maria Amelia (baptized 12 July 1746).
Adolph & his wife, along with their sons and son's families, immigrated to Schleswig-Holstein (Denmark) where they settled in Flensburg on 17 May 1762. They left Flensburg on 10 June 1763.
This family arrived in the colony of Messer on 7 July 1766. Adolph and Maria Elisabeth are recorded there in Household No. 11 on the 1767 Census, son Philipp and his family in Household No. 5, and son Adam and his family in Household No. 9. Daughter Maria Amelia and her husband (Simon Voigt, whom she married in route to Russia in Danzig on 2 June 1765) are recorded in Household No. 14.
There is also a Jacob Manweiler, age 19, recorded in Household No. 12, on the 1767 Census of Messer , but he is not found in the records of Meisenheim to be a son of Adolph & Maria Elisabeth. There is a Johann Jacob Manweiler of the right age, the son of Johann Nikolaus & Anna Margaretha Manweiler, who was baptized in Meisenheim on 12 July 1746. The relationship between this Johann Nikolaus Manweiler and Adolph Manweiler has yet to be established. They do not appear to be brothers.
Descendants of the Adolph Manweiler family are living in Franzosen by the time of the 1798 Census of the Volga German colonies.
