I have a document on the letterhead of Nicholas Dininni of Harrisburg, PA, June 3, 1985, that verifies your information.I don't know who he is, this came through my husband's cousin. It starts with Joh. Marx Wallauer of Obermaschel, which is located approx. 9 miles SW of Bad Kreuznach, Germany.B K is about 45 mi NE of Frankfort.Joh. Marx and Charlotte had one known child, Joh. Leonhard.The dates of sailing and arrival are the same as in your info.The Dragon sailed from Rotterdam to England then to Philadelphia."Joh. Leonhard took the required oath of allegiance to the King of England."
This is our line.The document goes through the generations and might be of interest to other researchers.
