Great grandmother was Gesina Tjarks married Edward Johnson in LeMars or Cherokee IA. Have old letter written in German stating Mary Tjarks born Sept 9, 1891. Greatgrandmother's sister. All of her siblings ended up in Sibley and Gibson city ILL. All of these Tjarks family came from Ostfriesland Germany. There is also Jensens in the family, but I do not know how they all connect. Any info would be great! Thanks, Marie
