Name Mary Stapanski (Doniecki)
Notes Phyllis Long added the death certificate:

Mary Staponski / Szczepanska
Abt. 1870 Poland - the Census has May 1864
May 29, 1930 Capps Creek Twp., Barry Co., MO

It reads that her birth date is unknown, age about 60 and that are parents are not known. Her husband was given as Antonio Stapanski, probably Antone. Antone Stapanski of RFD Monett, MO was the informant.

1900 Census Missouri; Barry; Capps Creek; District 3
Anton Szypanski, head, born Jan. 1854 Poland, age 46, married 14 years, parents born Poland, farmer, immigrated to US in 1881
Mary, wife, born May 1864 Poland, age 36, mother of 1 child, living, parents born Poland, immigrated to US in 1881
Frank, son, born July 1889 MO, age 10

This has to be the right 1910 census. Ages and years married all wrong. Mary would have gotten married at age 10 and Anton, age 15. Maybe couldn’t speak English and got it all wrong?
