“NINETY YEARS OLD
Mrs. Maria Bradley, the subject of this brief sketch was born in Mendon, N.Y. Her early life was spent in the beautiful town of East Bloomfield, Ontario county, N.Y. It was there she was maried to Harvey S. Bradley, and in May 1830 removed to this town with her husband and six children to make a home in the unbroken wilderness, settling on the farm now owned by Will Fry. After many years of toil and privations incident to pioneer life, they succeded in building themselves a comfortable home and sequiring a competence for old age, and as years went by and the children were grown up they came to feel the neccesity of changing their home for … where their cares would be less and consquenty removed to this village, where they could spend the remainder of their days in restful quiet. In May 1881 the partner of her life was removed by death after walking together for a period of sixty-four years.
After a period of three years she removed to Ypsilanti to live with her son Oliver, where she has spent nearly five years in the enjoyment of good health, having retained her faculties to a remarkable degree. She passed her ninetieth birthday on the eighth inst., two of her children being present. Few come to such a ripe age of whom it might be said, “She hath done what she could” and although willing to abide her tiem is anxiously waiting to depart and be with those who have preceeded her.
’Beautiful lines are those that bless,
Silent rivers of happienss,
Whose hidden fountains, but few
may guess.”
[Northville Record, Friday May 17, 1889, p.1, c.4]
