'John, eldest son of Nicholas Erb, ... married a Johns from Leacock township, lived for some time with his father, but subsequently moved near to Manheim, where he died.'
NOTE: "Johns" is another form of "Shantz" (this source also identifies the husband of John's sister Magdalena as a "Johns" of Leacock township).
'Hans Erb [son of Nicholas Erb], b. 13 Mar 1713. He died at Manheim Township, Lancaster County 13 Jan 1778. ... He married Barbara Schantz, who arrived on the same ship as her [future] husband in 1737.' Their first child was born about 1746.
13 Mar 1713 is his baptism date, as indicated in an email from Richard Davis.
