He married Anna Margaretha Hirtzel in Germany and they apparently had two children before they immigrated to Pennsylvania. They had seven recorded children. The childrens' surname is given as Lieb.
The seven recorded children were Ester, Johannes (Jonas) (September 30, 1725, in Reihen, Baden, his mother's birthplace), Margaret (1728, after the immigration), Elizabeth, Susan Catherine, Johannes Godfrey, and Maria Barbara.
According to W.A. Schwartz, the family arrived in Philadelphia from Rotterdam on September 18, 1727, aboard the William and Sarah commanded by Will Hill "with a colony of about three hundred Swiss-German immigrants"[1] led by a Reformed (Calvinist) minister, George Michael Weiss, "the first fully ordained German Reformed minister in America."[2]
The ship's log lists "Johannes Gdfryt Leyb" as the head of a family of four.
"Johannes and Margaretha apparently remained in York County, Pennsylvania, for the duration of their lives.
"Johannes (Jonas) Leipp was the oldest son. According to a Lipe family history, Johannes Godfrey Leib was the first child of Johannes and Anna Margaretha born in this country." [He was the first and only recorded son born in America, but the dates suggest his sister Margaret was the first American-born Lieb, and two more sisters were born before Johannes Godfrey.]
2. According to Wikipedia, George Michael Weiss (last name also spelled Weitzius) was a Dutch Reformed clergyman[?] "born in the Rhine Palatinate, Germany, in 1697, and died near Philadelphia in 1762," who worked in New York and Pennsylvania.
"He was ordained to the ministry at Heidelberg in 1725, and two years afterward emigrated to the United States with four hundred settlers. He went with them to Pennsylvania, organized a Reformed Dutch church at Skippack, returned to Holland, and collected funds for its support. He became pastor of German congregations in Schoharie and Dutchess Counties, New York, in 1731, and labored there fourteen years, but was compelled to flee to Pennsylvania to escape the attacks of the Native Americans. From about 1746 until his death he preached in Old Goshenhoppen and Great Swamp, Pennsylvania." (Skippack is north of Philadelphia, about a hundred road miles east of York. Great Swamp seems to have become Quakertown, north of Skippack, as is Old Goshenhoppen; there is an Old Goshenhoppen Reformed Church in Harleysville.)
