In 1918, Jigger Bob was in the Indian Service Police and paid $20 per month.
Park uses Jigger Bob as a source in his ethnographic notes on the Northern Paiute.
His birth year has been reported as 1822 and as 1857, below is a discussion of his birth year.
- The 1900 Census reports that he was 50 years old and married to Juda Bob, age 40. 
- The 1910 census reports that he was 62 years old (birth year estimated as 1848) and married to Judy, age 50.
- The 1918 Indian Census has Jigger Bob being born in 1857.
- The 1920 census has Jigger Bob being 63 and Juddy being 59.
- In 1933, he was claiming that he was over 100 years old.
- Hermann states that there was a cross with the name Jigger Bobb on it and the date August 24, 1936 in the Nixon cemetary. However, the October 10, 1935 newspaper states that he had died before that date. . The Nixon Cemetary Findagrave site does not list him. Hermann states that that he lived until 114! 
- An October 10, 1935 newspaper article states that Jigger Bob died at the Stewart Hospital, presumably at Stewart Indian School, south of Carson City. The article states that he was said to have met Fremont's expedition in 1945. The article states that there are some doubts his claim of being born in 1822, it states that about 15 years previously (ca 1920), Major Creel (father of Cecil Creel of the agricultural extension service) spent several days on the reservation looking for an Indian who may have witnessed the 1860 battle where Major Ormsby was killed. Creel reported that he only found one, who at the time was a boy of 12.
