I don't know if you are still looking for information on this, but after many of years of looking I've figured out that a Matilda in my tree is the same Matilda you are looking for. Matilda Van Doozer was born in 1844 and married my 3rd-great grandfather, Nelson Bristol (who was also her uncle) in the early 1860s. They had two children, Eleanor and Caroline. Nelson and Matilda were divorced in Kewaunee County in 1873 and Matilda remarried Wesley Burns in 1874. I can provide some more details of this if you are interested.
