Re-reading these posts, I'm not sure if I gave you the new info. I have now found out that I did have 2 Robert Blair's in Wisconsin mixed up. My gr grandfather Robert died in Wisconsin in 1901 in Iron River, Wisconsin. He and Adeline did have twin girls, Jesse and Lidia born Dec. 31, 1883, along with another daughter Marie Louise born in 1882, and a child, unknown gender born and died in 1884. Adeline then disappears from Wisconsin and next pops up in New Hampshire. Not sure what she was up to for the next 20 yrs, but suspect she spent some of that time in Cahoes, NY. My grandfather Albert and Amanda were married and had 3 of my uncles in Cahoes. Also, Marie Jeanne Elisa aka Jane or Joanna's son Louis Ira Leduc was born in Cahoes in 1888, her other children were born in WI, I suspect she may have been visiting her mother Adeline when she gave birth to him.
So, still investigating "The Great Adeline Mystery".
