I did a quick look at the 1900 Census for Cherokee county, Kansas, take June 6, 1900.There is a George (Geo.) Dobson listed with a wife named Mattie if I understood the spelling correctly.They have a daughter, 11 months old, named Ethel, born June 1899.Not other children listed, but it shows the mother has 4 children with just one living.The couple married 8 years.
The Father is born Aug. 1868, age 31, born in Missouri and his father born in N. Carolina, mother in Mississipp1. Mattie, the mother born March 1874, age 26, born in Missouri, mother and father both born in Indiana.
So this sort of fits except for the mothers name.
I hope this helps.Can you access the census records?Try Heritage Quest Online for one, it might be available through your local library. If you email me I can send you an image of that page of the census.
