In July 1905, John Perry Campbell from Rhinelander WI had surgery at a sanitarium in Battle Creek. When he died in 1906 in Rhinelander, his obituary stated "he had no known relatives except a brother & sister in Michigan." I am trying to find that brother & sister and have no other clues. John Perry was b. in 1834 in New York state, son of William Campbell & unknown mother. I presume his surviving brother & sister were older than he was because I know of his younger siblings, and were also born in New York. Is there anyone who recognizes this family?
