there seems to be some sort of confusion as to the birthyear of Michael and Martin. if I put in 4/7/1794 for Michael and 10/5/1793 for Martin a red block at the top of the page will show up stating the unlikelihood of a birth within 8 months. yet, the records I have found on familysearch in several spots, by others, show those 2 dates. I don't know how sources can say for a fact that he was born less than 8 mos after Martin H. was, but I didn't find anything to dispute it. check it for yourselves...
