John Adam, our immigrant ancestor, was probably single when he came to America in the 1750's. The exact date has not been established. By 1758 he and his wife, Anna Maria, (maiden name unknown (believed to be Strohecker )) were living in or near Reading, Cumru Township, Pennsylvania. No marriage record was found, but as man and wife the presented a son, John Jacob for baptism on 5 March 1758 at Trinity Lutheran Church, Reading, Pennsylvania.It appears that John Jacob was born almost a year earlier, place uncertain. The 1763 Weiser lot list of Warrants and Patents for Reading, Pennsylvania shows Adam Wurtemberger's name in relation to Lot # 335 on Clement Street in Reading. His name appears within the outline of lot # 335 on the City Plat Maps but no date of patent is provided as appears for most of the lots. (Reference: Internal Affairs Monthly Bulletin, Commonwealth of Pennsylvania Vol. 22, #6 and 7 May-June 1954 pp. 11-22).
  John Adam Wuertemberger and wife, Anna Maria, were sponsors at the baptism of John Adam Zimmerman on 18 May 1764 at Trinity Lutheran Church.
  On 15 September 1782, Adam Wuertemberger, widower, and daughter, Mary (birth abt. 1766), partook of the Lord's Supper at Trinity Lutheran Church. Therefore, it is presumed that Anna Maria had died sometime between 1764 and 1782. This was the last entry for John Adam, Sr. in the records of Trinity Lutheran Church, Berks County, Pennsylvania.
  No death or tombstone records have been found for John Adam, or his wife, Anna Maria. A burial ground, adjacent to the Old Church House, is now beneath part of the present church. A record of the old stones did not include the Wuertemberger name.
  According to the Church Secretary, John Adam Wuertemberger was not among the founders of Trinity Lutheran Church in Reading. The family name was not found in the records of the church til after 3 November 1790.
  Tax Records for Cumru Township, Berks County, Pennsylvania for 1781 lists the following:
     Adam Wortemberger, stocking weaver;
     Jacob Wertemberger, stocking weaver;
     Adam Vortemberger, single, freeman.
These were, no doubt, Adam, Sr. and his two eldest sons.
  Stocking weavers, and others able to produce finished goods, were much in demand during and after the Revolutionary War. Prior to that time the colonies were expected to supply England with raw materials, and were mostly prohibited form engaging in the manufacture of finished goods which were instead purchased from English firms.
