Rolfingsmeier

I am researching the family history of ROLFINGSMEIER. Information I have shows the name to have started as ROLF in mid 1700's, in the Wehdem church records, Westrup area. Records have shown it as ROLFE, ROLFES, MEIER/ROLFES, ROHLFING, ROHLFINGSMEYER and finally ROLFINGSMEIER.

*Claus Herman Rolf or Rolfes (b. 1744 d. 1800)
     (my g-g-g-g-g-grandfather)
     -married Margarethe Elisabeth Wiese or Wisen
           -b. #3 Wehdem 1742 d. 1808
     They had 5 children, the 2nd child being-

*Gerd Heinrich Rolfes or Meier/Rohlfing b. 1773 d. 1843
     -married Marie Margarethe Eleonore Schmidt
           -b. #46 Westrup 1769 d. 1823
     They had 4 children, the 2nd child being-

*Johann Heinrich Rohlfing or Rohlfingsmeyer
     -b. 1803 d. ?
     -married Marie Elisabeth Heldmann b. 1808 d.?
     They had 5 children, the 1st child being-

*Johann Friedrich Wilhelm Rohlfingsmeier
     -b. 1825 d. 1872
     -married Anna Elisabeth Oelze b. 1829 d. ?
     -Johann emmigrated to America, settling in the Plum
        Hill, Washington County Illinois area.

I am searching for the parents of Claus Herman, and any siblings or relatives. My searching has hit a brick wall with Claus Hermann. Not sure if they are from Wehdem, Westrup area. Any help would be appreciated.
