I found this in the New Jersey State Archives in Trenton in Feb 2007. Alvina died April 15, 1918 in Presbyterian Hospital of obstructive jaundice secondary to gallbladder disease. She was only 52 years old, born Oct 7, 1865 in New York. The names of her father Gustave Roemhild (Germany) and mother Mary Hauckouf are consistent with the information on her birth certificate. (The birth record appears to state the Mary was born in Europe.)  Alvina was buried in Lutheran Cemetery. We see the 1918 signature of my Grandfather Gustav Insel.

Sometime between 1866 birth of Alvina and the 1875 birth of Lillie, Mother Mary Hauckauf may have died. This deserves another search of the NY Archive for a death or wedding!
