My Ancestors were Henry and William Hemesath, from Hanover (possibly Osnabruck). They had a sister - Elizabeth and a third brother-Frank. Elizabeth moved to Winneshiek Co. with Henry and William. Frank remained in Cincinnati OH-working for Proctor and Gamble. We have lost track of that segment of the family. Frank retained the spelling "Hemsath"-The Winneshiek Co. family legally returned it to the original "Hemesath". I have a very detailed history of our family from Henry's generation on. I have very little before that. I hope this helps. If this is the family you are looking for, let me know. I can invite you to our website that has the family tree on it.
