I know the names are spelled different but hope maybe there is another Hartke out there looking for a match. My Hartkes came from Hanover Germany from the towns of Furstenau, Voltlage and Kalinghausen. They arrived in the 1840's and most settled in the Cincinnati, OH--Northern Kentucky area. My greatgrandfather owned Joseph Hartke and Sons Carriage in Covington, KY. His uncle founded Hartke Hardware in Cincinnati OH. Anyone interested in exchanging information can write Froelicher @aol.com Be waiting to hear.
