I don't have any information on your Maltby line, but since your inquiry was so long ago, I am curious what you have discovered in the last 15 years about your Maltbys? My gg grandfather, Godfrey Nelson, evidently lived in Maltby, Hubbard County, Minnesota at one time while also living in Park Rapids between 1890 and 1944. The name must be tied to your family. I don't know the area at all, since I live on the west coast. Do you have anything you could share about the settlement of Maltby, Minnesota?
