Barbara,
There is no Fredericka Moehler. I believe it is a mistake for Frederique Moog.
You can find in Lembach records all the names you attribute to Fredericka Moehler:
Frederique Moog (known as Fannette), born 18 Jul 1803 as Frommet, daughter of Isaac Schmulen (took the name Moog in 1808) and Jeannette Dreyfuss. She married firstly Joseph Levi and was a widow in 1819; she married (1821 in Lembach) Salomon Meyer, born in Niederhochstadt. She had 13 children during 25 years, all born in Lembach:
Moïse Meyer, 11 Sep 1822
Nathan Meyer, 22 Jul 1824
Abraham Meyer, 1 Mar 1826
Jeannette Meyer, 5 Mar 1828
Louise Meyer, 25 Feb 1830
Samuel Meyer, 20 Oct 1831
Lazare Meyer, 11 Mar 1834
Lion Meyer, 5 Sep 1836
Judith Meyer, 20 Apr 1839
Sophie Meyer, 25 Jun 1841
Isaac Meyer, 30 Mar 1843
David Meyer, 21 Apr 1845
Simon Meyer, 19 Apr 1847
She died 18 Apr 1848
I hope this helps,
