I have recently been exposed to the history of our family here in Osage County Kansas.My mother, Jeanie Wallace has a copy of the Mickelson family history that I believe is your work.
I've also recently reconnected with Kathy Mickelson in Lyndon.She and I have known each other for years, being teachers in Osage county, and I just interviewed for a job with the Coop where she works.
Regardless, my mother is connected to Lars through mostly maternal branches in the tree.
If I recall correctly:
My mom Jeanie is daughter of Broder "Bud" Williamson, son of Soren "Sern" Willaimson and Ida Broderson, Ida the daughter of Christina Mickelson Broderson, daughter of Lars
My mom enjoys the history of the family and would, I'm sure, discussing it with you. She may even have some information you don't have about the Brodersons.I know you are connected to the mickelson buried in Lyndon and Ottawa, Ks. Over memorial; day mom and I and one of my osns visted the lyndon cemetary and used pictures to find markers.Outside Lyndon, (on the way to Melvern)there is a tiny danish cemetary where the first "American" Brodersons are buried.(Peter)
I'm passing this forum on to her so she can also register and learn more.I hope this exposes you to new information.
