Hi Jan
My name is Henri De Munck and I live in Toronto Canada
Although I cannot help you with Sheree Guth, I thought I would let you know we are distantly related through marriage.
Back in 1843, Carolus Ludovicus De Munck was born.
He had several children, no.1 was Petrus (1871) and no.4 was Frederik (1876).
Frederik De Munck (Maria Speeck) as you know emigrated to the U.S. in 1903.
Petrus' son Henri De Munck (Magdeline D'Hooghe), my grandfather, emigrated to Canada in 1926.
My grandfather died young in 1946, and my father never knew he had a great uncle in the U.S.
If you find additional info. on Frederiks family, please let me know.
Regards
Henri
