Named in movement records relating to his sons Joachim and Marcus; both records cite the same family number and consecutive individual numbers.



A movement record from 1841 names his wife and gives the ages of sons Hirschel (45 or 46 years) and Joachim (30 years). On this basis Hirschel would have been born 1794-1796 and Joachim would have been born 1810-11; the latter is clearly impossible since Joachim's first son was born in 1815; it is likely that "30" is a mis-transcription of "50", placing his birth in 1790-91.
