Genealogical records state that Theron Wells Crook was born on March 12, 1816 to Asa Crook Sr. and Mary Dustin of Prophetstown, IL. He married Nancy Hamilton. However, this photograph identifies his wife as Ida. I have no information concerning Nancy or Ida in family lore. UPDATE: From the internet I learned that Nancy was 20 years older than Theron. This may be why a younger wife named Ida is identified in this photo. Nancy is listed as having died in 1853 in Illinois. In other words, she may never have made it out to Oregon or California. [Nancy Alvira Hamilton born May 6, 1816; m Theron Crook March 3, 1836 (Knox Co IL).]
