My Grandfather Henry Adolph Hanson is in the back row, 3rd. from the left.
 He married Marie Larson. Both died in Richmond, CA in 1947

From left to right, I believe are his siblings, Laurina (b. 1879 -m. Mathias Mathison)
 Hans M. (b. 1866 -sitting), Albert (b. 1875), Henry A. (b. 1882), Carl M. (b. 1869 -sitting)
 and Mary Marie (b. 1872).  Would like to positively identify the other persons.
