Abraham ? Fürth

I propose that this profile is of Abraham, brother of Ephraim and son of Samuel Furth, and that he is the same as this Abraham: Abraham Fürth This is based on a) my direct ancestor being Abraham Fürth (died 1810) and b) that I have inherited documents of Ephraim Fürth, son of Samuel and that one of these documents from 1775 relates to ABraham, son of Samuel Fürth. I am looking for proof before merging the two profiles. [Peter Lowe 10 Sep 2014]
