Just thought I would look around and try to help you out. Looks like Minnie's parents are George James Brundrett b.Nov 1856 in Massachusetts d. about 1915 in Cass County, MN. Her mother was Mary Hannah Beckman b.20 Feb 1868 in Springfield, IL and died 23 Feb 1942 in Modesto, CA.
Her grandparents were Thomas Brundrett b.1819 Eng and Hannah b.1822 Eng. On mother's side, Samuel Morgan Beckman b.12 May 1845 Lee, Brown, IL d.7 Jun 1905 Jenkins, Crow Wing, MN and wife Mary Jane Whitney b.Jun 1847 Springfield, IL and died 29 Apr 1931 Wabedo, Cass, MN.
Let me know if you want me to attempt any brick walls, I just cracked one on my family that's been a mystery for 40+ years. Luckily an obscure book at Harvard was available online which solved it.
