"I was born and grew up in Pittsburg, KS. I now live in Carthage, MO, just about 35 miles from Pittsburg. My mother still lives in Pittsburg, so we go there fairly often.
"My great-aunt, Agnes Cunningham, married Nestor Mingori on June 14, 1947, in Pittsburg. He was known as "Tubby", even though he wasn't a large man! They lived in that area until they died. Agnes died in June 1985 and Nestor was still living at that time. I know that since then, he has also died, but I don't have the date or his obituary. I have Agnes' obituary.
"The next time I go to Pittsburg, I'll see what I can find about Nestor. Agnes was previously married and had two children from her first marriage. One of them still lives in Pittsburg and can probably tell me lots about the family. Agnes did not have any children after she married Nestor.
"I imagine that some of the family worked in the mines in the Frontenac area, but I don't know his parents or how he is related to the others you mentioned. If you have any information on Nestor or his ancestry, I would certainly appreciate having it."
