I discount your information that David Barrows was born in New York. The year 1850 was a time of slow migration from New England through New York to Michigan ("Michigan Fever"). See Kuhn, M. History and Culture, pp. 99-106. In Sommers, L.M. (Ed) Atlas of Michigan. East Lansing, MI: Michigan State University Press, 1977. David may well have been born in New York and then moved in early childhood to Michigan as his parents availed themselves of the agricultural productivity of Michigan's climate (moderate relative to New York) and deep rockless soils in expansive flat expanses, purchased at low prices, as well as inexpensive transport across Lake Erie through the Erie Canal (completed 1825) to New York City markets. Many of my relatives acted on this Michigan fever.
