How did I find both? I stumbled across these two records by looking for the census entries for all of his children- not just the one from whom I descend.
He is listed with his wife, Catherine [Donnell], two daughters, and four grandchildren in Hackettstown, Warren County, New Jersey.
|Preston, Michael. Preston, Catharine. Preston, Hannah. Preston, Catharine.|
Ultcht, John. Ultcht, Catharine. [Children of Charles P Ultcht and Anna Preston]
Walsh, Joseph. Walsh, John. [Children of Jeremiah Welch and Mary Preston]
He is also listed in the household of his son, John, in neighboring Independence.
Michael is married in one listing and widowed in the other. This value in this double enumeration is that we can hone in on a death date and location for Michael's wife, Catherine Donnell. In 1899 or 1900, the family relocated from Dutchess County, New York to Warren County, New Jersey. Catherine was alive in the 1880 census; finding her husband listed as widowed and married in 1900 in New Jersey should narrow down the search for her death record to one year and one state instead of twenty years and two states. I have, however, been unable to find a record of Catherine's death in either state.
Michael again moved shortly after the 1900 census. He died in Bayonne, Hudson County, New Jersey in 1904.
