Swedish variations of """"William""""

[Nancy Wiberg Jones]

I am trying to decipher the Swedish name of my uncle William Wiedow.  The 1930 US Census lists him as Wilmara or Wilmars Wiedow.  I can't quite make out the handwriting.  Is there a Swedish variation of William that would fit these spellings?

[Bertil Friberg]

Nancy,
The ordinary Swedish name for William, is Vilhelm or Wilhelm. I have never heard of a Wilmar or Wilmara. A name Wimar exists here but it is definitely very rare.

[Joakim Ekberg]

According to SCB (the Swedish Statistical Institute), there are presently 183 Vilmar, 212 Vilmer, 49 Wilmar and 355 Wilmer in Sweden, though none at all with the -a or -s endings.

Just a note on the last name. In the national phonebook (which is available online) there's noone with the last name 'Wiedow' in Sweden.
