Dear Jackie,
Do you know that there is a very large branch of the Lemmens familie thus the Nielen family living in and around Greenbay, Wisconsin. There is a small museum there in De Pere and that is where I found a deathcard of Henry Lemmens born in Venray, Netherlands, who came to Greenbay around 1860 with his first wife who died after a couple of years without issue. He then married a Dutch 16 year old girl and had about ten children.
Regards from Wadhurst, East Sussex,

If you want their descendants please contact me.
Sincere regards,
Gerard Lemmens
