Sometimes, it pays to write....

On mom's side of the family: Her father was named Anton, too, just like dads' father, so we took to calling them "Little Grandpa" (Janson) and "Big Grandpa" (Hesch).
Little Grandpa was one of 8 children (4 girls and 4 boys). Of the girls, Rose and Frances married, while Anna and Sophia became nuns: Sophia was born in Germany (1875), and became Sr. Lazara, and Anna was born in Minnesota (1883), and became Sr. Kunigunda.

They belonged to the Franciscan Sisters in Campbellsport, Wisconsin, so I emailed the contact person on their website. In a few days, I received an envelope with these photos from the 1930s, and their birth, first vows, final vows, and death dates. Sr Lazara was a homemaker and died at 78 years old in 1954, while Sr Kunigunda was a teacher and died at 90 in 1973.
They're buried at the Sisters Cemetery in Campbellsport, Wisconsin.
