Hello. We are looking for a limb of our family tree that appears to have no roots.My great grandfather was Frederick Lassin.He was married, and had children however the wifes name seems to be remembered by the grandchildren differently. No one knows what happened to the wife of Frederick Lassin.The information that I do have about him is that he was born May 29, 1897. His wife, whose name could be Magdalene, Margaret, or Marguerite, was born around 1897 and died sometime around 1943. Any information would be greatly appreciated.
