Hi everyone.I am trying to locate my family.My grandfather was Nicholas Theisen (born around 1856/not sure of date) from Luxembourg born to Xavier Charles Theisen and Suzanne Theisen. They could have lived near Rudelange. Xavier Charles Theisen was an adopted child.I am told the family was very large he was born into but very poor and couldn't aford to keep all the children.I am traveling to Luxembourg soon and would love to actually find my ancestors. Any ideas where adoption records can be accessed? or links?Thank you.
