Searching: Katharine (Katie) Maul, nee Kolder/Kolter married my Grandfather Friedrich MAUL in 1896 Manhattan. She appeared in June 1900 census with my Grandfather living with the Haffey's at 2225 Washington Ave, Bronx, near Fordham Univ. I believe Katie was related to the Haffey's living in the same housedhold. After June 1900 Katie disappears. What happened to Katie the 1st wife? No death certificate in NYC from 1900-1910. GF remarried Dec 1907. All help welcome. Ed
