"History of Barron County," published 1922, lists three Hulbert families (with the "e") in its biographical index: Azro I., David B. and Frank A.
However, there seems to be no mention of the given names you mentioned: Lloyd Joseph, Elmer, Gordon or Edith. There is very likely a connection. Some families chose not to be listed in this book, including my grandfather who felt it constituted "boasting!" (Drat!)
I can copy some of the given names it does list in these families if you think you might see something familiar. The section on Frank A. Hulbert it quite lengthy and credits him with a "varied and adventurous career."
