Happy to hear you found something on your family. Personally I have nothing further. I do a lot of typing for various counties so people will have some free information on the web.
I did do some checking of census records and I found J Calvin living with his parents for the 1910 and 1920 census, could not located them for 1900. Perhaps their surname is so badly misspelled for that year.
