'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.
'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).
