I am working on an "all descendants of" database for John Michael Lambert, born 1744 in Garrweiler, Germany; married abt. 1774 to Rosina Strauss (?-1831); died abt. 1825 in Nockamixon Township, Bucks County, PA.
Their children and the spouses of their children are:
i. Nicholas Lambert (1775-1852) md. (1) Elizabeth Lehr (1771-1837),
(2) Eve Lehr (c. 1780-?)
ii. John Christian Lambert (1777-1853) md. Sarah Deemer (1774-1849)
iii. Barbara Ann Lambert (1779-1861) md. John Kohl (1779-1860)
iv. John Lambert (1780-1868) md. Elizabeth Heckman (1785-1872)
v. John George Lambert (1782-1876) md. (1) Magdalene Mill (1785-1823),
(2) Margaret Fehr (1789-1866)
vi. John Leonard Lambert (1784-1876) md. Maria Nicholas (1789-1865)
vii. Michael Lambert (1785-1869) md. Elizabeth Pearson (1785-1871)
viii. Rosina Lambert (1787-?) md. Peter Strauss (?-?)
ix. Elizabeth Lambert (1788-1860) md. Peter Lehr (1787-1864)
x. Mary Magdalena Lambert (1790-1869) md. Peter Ripple (1776-1852)

xii. Sarah Lambert (1794-?) md. Isaac Strauss (?-?)
xiii. Maria Lambert (1796-1834) md. Jacob Ziegenfuss (1789-1872)
Most stayed through the early generations in the Bucks/ Northampton/ Lehigh County, PA areas, although Mary Lambert/ Peter Ripple and Catherine Lambert/ John Shoemaker are known to have moved to the Montgomery County, NY area. The descendants and whereabouts of Rosina Lambert/ Peter Strauss and Sarah Lambert/ Isaac Strauss are largely unknown.
Surnames common in the file include: Applegate, Brotzman, Eddinger, Fluck, Frankenfeld, Fulmer, Hartzell, Hellick, Kichline, Kohl, Leh, Lehr, Nixon, Ripple, Roth, Ruth, Seiple, Shoemaker, Sigafoos/Sigenfoos/Ziegenfuss, Smith, Steele, Strauss,
Thatcher, Thomas, Tintle, Transue, Ummel, Unangst, Weber, Wilson, and Wolbach.
The file currently has about 2,500 names in it, and I am always looking for more. Willing to share all info.
