MarieLynn, I am sorry I did not see your post until just now. I have looked through my records and don't see anything matching the people you inquired about. There is one tie between the Roskamps and Leemhuis families but that was in the Weener area. I know there were lots of Roskamps in the Netherlands. Most are not connected to mine, however. You might check and see if the LDS church has films for Holtgaste and trace them that way. Also there is a great site for the Netherlands at Genlias.nl that has many civil records. Good Luck with your search. Carrie
