Thank you Jonathan and Leigh Anne, for your comments. I just spent some time reviewing Parts I, II, and III of the Bittinger articles. In Part I, on page 119 he wrote "Jacob Bowman is believed to have immigrated in 1737, first settling perhaps near the town of Lebanon, moving then to York County, then to Maryland." Bittinger did not mention the Charming Nancy. On the same page Bittinger states "The earliest ancestors for this Bowman line are Jacob Bowman (ca 1718-1802) and his wife Varena, who were living in Washington County, Maryland, from around 1750 to around 1778." This is a clear indication that Bittinger had no further information about the parents of Jacob Bowman-862.
I did see a copy of the ship's list from the Charming Nancy, taken from Pennsylvania German Pioneers by Ralph Beaver Strassburger, Vol III, page 196, that shows a German script signature for 'Jacob bauman' who arrived in Philadelphia 8 October 1737. Varena's name is not on the list.
In addition to the recommendations I made on March 26 and which I will now complete, I believe that Jacob's first wife Varena's name should be changed to Varena Unknown instead of "Verona-5". She apparently died in Frederick County (which later became Washington County) Maryland about 1771. Her first child, Jacob Bowman-2073, was born about 1740, so they were likely married about 1739, probably in Pennsylvania. Her husband was born about 1718, so 1720 appears to be a reasonable birth year for her, married at age 19, first child born when she was 20.
