Is there any compelling reason not to merge with Karoline Kohn , given
1) This Karoline Bohm was married to Samuel Kohn, had several children in house #46, and became a widow in 1861.
2) Ferdinand Kohn was born in house #46 to the widow Karoline Kohn geb. Bohm in 1868. No father is listed on his birth record and his birth was uneheliche, though the name Samuel Kohn is mentioned (apparently in error or as a white lie? though there were other Samuel Kohns in town at the time) in later records. His biological father is therefore uncertain.
3) Although Karoline's father is called Jakob in Ferdinand's birth record, this seems likely to be an error. Eduard's birth record, similarly, has Jakob Bohm written in, and then crossed out and replaced with Isak. There is a birth record for only one Karoline Bohm in Klum in the relevant time-frame.
