My great-great grandmother, Sophia Krohn, was born in Mecklenburg, Germany in 1835. She married David Willfang (Wildfang, Wilfong etc).They farmed in Bruce County, Ontario, Canada after moving there from Waterloo County, ON. I would expect that Heinrich, born 1825, was a first cousin of Sophia.Sophia's dad was Christian Krohn. They came over about 1851 apprx. and were shipwrecked and rescued on the way over. Last summer I visited some Krohn relatives north of Waterloo. Those Krohns live in Windsor.
