Looking for information regarding my husband's grandmother, Mary Hadler born approx. 1860 in Ontario, Canada, died 1938 in Brockport, New York. Her father was Charles (Carl) Hadler born 1836 in Mecklenburg, Germany. Married Louise ? born approx. 1838 - 1839 also in Mecklenburg, Germany. Charles and Louise immigrated to Canada before moving to New York state. Any other information would be greatly appreciated.
