I am looking for any info on Hartz. This is what I have:
Jachim and Charlotte Hartz born in Schleswig Holstein, Germany and came to US in 1866 and moved to Daven port Iowa, along with their children, one of whom was Henry Hartz. Henry was b. 2/23/1850, d.11/22/1904, married Sophia Buck, had 10 children, one of whom was Otto Hartz, b.3/28/1880, d.01/29/1965. Otto had 5 children, one of which was Arline Hartz, whom married Rinnie Dietz in Colorado. This is my grandfather.
I am not good at the research thing, so any help will be much appreciated.
