This is my paternal grandmother's mysterious grandfather, Jules Joseph Carre, born about 1855 in Belgium.
Carre married an Irish immigrant, Anna E. Degnan, and had two children in Rockford, Illinois, before vanishing around 1881. He turned up in Green Bay, Wisconsin, where he married an unknown woman and lived with her for about 12 years. In 1896, he returned to Belgium to see about his late father's estate, and while there married another unknown woman.
A newspaper article found at GenealogyBank.com detailed how a "letter of inquiry" from Belgium alerted Wife No. 2 that Carre was married in Belgium. Her investigation led to finding out about Wife No. 1 back in Illinois.
She married a man named James Warwick of Green Bay. Wife No. 3 in Belgium discovered the bigamy and ousted Carre. He returned to Green Bay to find Wife No. 2 remarried.
The newspaper article ended with the statement that none of the three wives wanted Carre, and that he was homeless. It did not mention their names or give any other information.
I'm curious to know whether anyone knows who the second wife might have been, and what happened to Carre (whose real name was actually Lequarre or Lequiere). A search for James Warwick has been inconclusive.
