The Springer Heirs Hoax has muddied the record concerning descendants of Charles Christopher Springer, but the record seems clear (see "Charles Springer's Family in Swedish History" by Baldwin Maull, and Ruth L. Springer's article in the Delaware Historical Society dated Nov. 1982, p. 85 on the Springer Family) that Jacob Springer, b. 1750 at Christina Hundreds (Wilmington), baptised 23 Feb. 1750 (H. T. Bk 3, pg. 809) m. Margaret Gregg. Jacob d. abt. 17 Apr. 1817 in E. Pike Run Twp., Washington County, Pa. (Prob. of Will, Wash. Co. Bk. 3, p. 145). There is also a note in Ruth L. Springer's article that "A family letter written in 1832 says that Margaret (Gregg) Springer continued to live in E. Pike Run Twp."). So, it looks like Ruth Springer did some actual research on Jacob's origin. I obtained Ruth Springers two-part article on the Springer Family directly from the Delaware Historical Society. As you must know, Springer is a German name (Charles Christopher Springer's father was a German who married a Swedish lady of the court of the Queen (Hedwig Elenora) of Sweden and Charles was a result of that union). It is highly unlikely that a Jacob (James) Springer came directly from Ireland. There was a Jacob Springer who emigrated aboard an English ship in 1737, but he was a German and was 32 yrs. old when he arrived in Philadelphia to take the pledge to the King of England.
