Here is the page from the Kansas guardianship of John F. Rockers, age 4.
The man is listed as John G F Moeller in the Kansas record.
Here is the Missouri estate settlement record listing the heirs. Notice in Missouri the name is written as Moller. J G Moller died Intestate and George T. White, Attorney at Law, was appointed Letters of Administration.
I cannot read the name of the deceased heir, * H. Moller. The first letter is not 'J' but could be an 'A' as there was an Anton Moller in Jefferson City.
I then found this Notice of Sheriff's sale listing the heirs.
Mary Moeller married John B. Schneeders. I haven't identified Anne M. Moller but did find her in the census with the children listed here.
So, was John G. F. Moller/Moeller a brother, uncle, father or grandfather to the heirs? Harman H. Rockers married Margaret Anne Mueller at St. Francis Xavier Catholic Church in Taos, Cole County, MO on 11 June 1861. I haven't been able to identify the burial place for John Moller. There is a will for Johann Gerard Moeller but it was written in 1868.
I will be visiting the church above later today. Any suggestions??
