Johann Adam Ickler, born 26.02.1836 emigrated in 1869 to America. One (or two) year(s) later his wife Maria Elisa (nee Eckhardt) emigrated too.
This information is from the emmigration-records of the small town of Goßmannsrode, Hesse, Germany. I am, as far as I know, not related to any of these people but I hope this information may help present and future researchers.
