Note: Howard is a surname I research; however, these Howards are not part of my family. As seen at FamilySearch's New York, Land Records, Livingston Deeds, 1819-1828:
Laban A. Howard, M.D. who was born in Livingston County, New York, on September 22 1841, was living in Hillsdale County, Michigan. His bio stated that his father had also moved to Michigan.
Mary, the widow of Laban Howard, was mentioned as the wife of John Glasgow, also in Hillsdale County, Michigan, to wit: "John marr. third: Mrs. Mary A (BABBET) HOWARD, widow of Laban HOWARD."
