Re: Info. on Father Gregory Sontag of Mankato\

Appreciate information on my grand cousin Gregory. My research shows that he had a sister Josephine b.Mar 18, 1888 - d. Apr 20, 1926 Mankato,MN. His brother was John William b. 1886 - d. 1958 Mankato. Their parents were Englebert H. Sontag and Franuska Robel of Mankato. Englebert H. father was Heinrich J. Sontag one of the first pioneers of Mankato, MN. Father Peter Sontag died in India, Sisters Damascene (Frances) and Remigia (Mary Josephine) died in Wabasha,MN.
Please let me know the date of Gregory's death if you have it. Thanks
