Henry L. BOYD and Mary Mahoney BOYD moved from County Cork, Ireland > New York > Waupun > Le Roy, Mower county, MN. They are in Waupun in 1855 and 1860. The family is in Minnesota in 1865. Three of their children are last listed in 1860 in Waupun, and then are missing from the census when they show up in Minnesota. Can anyone suggest where I might find out what happened to them?
The children I am looking for are:
William BOYD born 1855 in New York, Andrew BOYD born 1858 in New York, and an infant (unnamed in census) born approximately February of 1860 in Waupun.
The family belonged to the Church of England in Ireland.
Thanks for any suggestions.
