I also want to thank you - Samuel A. Essex born 1840 in Green Camp OH, husband of Matilda and son of Samuel and Nancy is my great great grandfather and I've been trying to sort out the plethora of Samuel Essexs in the mid nineteenth century - still not sure where father Samuel came from - there is a marriage record online from Marion OH in 1837 which has Samuel and Nancy marrying, but I haven't found them on the 1850 census - I see a Nancy living alone with 2 daughters next door to a John Essex, who has a Samuel (or Lemuel) of the right age living with him - not sure what was going on there.
