My g-g-g-grandmother was Dorothea Gamm, born 1801 in Mecklenburg, now northern Germany.
She married Jasper Falkenhagen (Jasper is his English name, I suspect Carl or Johann) in 1827. They had at least five children in Germany, Carl, Johann, Dorothea, Sophia and Caroline, between 1830 and 1842.
The family emigrated in the mid-1850s, settling in Welland County, Ontario, Canada.
If anybody has any information on Dorothea Gamm, her ancestors or descendants, I'd be thrilled if you'd drop me a note.
