Found her on the 1870 Whitestown, Oneida, New York census (img 71) as Mary Finger
age 30, keeping house.
Ann Mary Finger was the wife of Martin Finger, of the Middle New York Mills.
Saturday afternoon she sent her little boy on an errand which necessitated his crossing the bridge at the Upper Mills. Saturday afternoon was that on which young Veatch was drowned near the Upper Mills. Some neighbor informed Mrs. Finger that a boy had been drowned at the Upper Mills, and the surmise at once flashed into her mind that it was her son.
Mrs. Finger was in an advanced state of pregnancy, and the intelligence affected her painfully. She staggered and fell. The fall ruptured a vein in her head, and her brain was suffused with blood. Medical assistance was summoned.
Drs. Porter and Smith responded, but physic was of no avail. Mrs. Finger lingered along until 7 o'clock Sunday evening, when she died. The deceased was a daughter of Peter Wagner, of this city, and was esteemed by all who knew her, as an affectionate friend and a faithful wife.
