Augustus Ackerman b May 1851 was a DENTIST in Blue Earth City according to the 1900 census. Augustus married Lucy Ann Anderson b Jan 1853. Augustus and Lucy Ann had 4 daughters: viz: Flay b Aug 1880; Harriet b Nov 1882; Franc b July 1884; and Hazel b March 1887.
Apparently Dr Ackerman deceased after 1920 and Lucy removed to Minneapolis to reside with her daughter Hazel, who was at first a nurse at St Barnabus Hospital; and by 1930 was doing private duty nursing according to that census. According to one family tree Hazel married a Mr Bosshard and is inter in Riverside Cemetery having died June 25, 1987. Mr Bosshard doesn't APPEAR to be inter in the cemetery--although there MAY be no headstone.
On another NOTE
Lucy's SISTER Elizabeth Anderson b Jan 1859 married Charles W Constans b Nov 1857 and found in Blue Earth City in the 1900 census with son Victor b Nov 1889.
Information about the Ackerman's would be very nice.
While these are NOT my personal family tree, it is an effort to follow some of the folks who MIGRATED FROM Washington Co, NY---specifically in this case Putnam--the northern-most town in Washington Co, NY.
