I'm looking for information beyond what I can find online regarding the McMillen Family that I will describe--primarily because I'm trying to figure out the parents of John Marshall McMillen. The family lived in Perry (also Minburn?), Iowa about 1883-1891.

John Marshall McMillen born around 1846-1849 in Ohio--don't know where, don't know who his parents were.

John Marshall McMillen marries Harriett Shepherd in 1878 in Indianola, Warren County (marriage record online) I have a lot on Harriett's Shepherd family--and she's buried in Indianola.

First son Clinton born in 1879 in Glenwood, Mills County, Iowa--family seems to have been there only a short while

Second son Henry born in 1880 in Indianola, Warren County, Iowa, birth record for Henry and 1880 census confirm residence

A few years later (perhaps 1883) family moves to Dallas County, Iowa. Lived primarily in Perry. Third child (a daughter) Mary Frances was born in Minburn, Dallas County, Iowa in 1891.

According to Clinton's obituary the family moved soon after to Victor, Iowa. Hattie died in 1894--I assume in Victor.

So I'm hoping there's some other type of records that provided information on the family living in Perry from about 1883-1891. It's possible they had a hardware store or that Clinton and Henry worked at a hardware store because they opened a hardware store in Oklahoma.

Thanks!
