Read: - White Mountain Echo, 28 Aug 1926, p.10: among those watching a golf match at the Mountain View House (Whitefield, N.H., summer colony of "Brooklyn folk") "were Dr. Sinclair Tousey and Miss Elizabeth Tousey". [web] https://www.loc.gov/resource/sn91063243/1926-08-28/ed-1/?sp=10&st=text . This places his summer home at Whitefield, N.H., which agrees with the 1937 obituary's "Summer resident here" and the Morrison Hospital radium gift. The golf-club patents of 1921-22 fit the same picture. - New-York Tribune, 6 Nov 1905, p.11, "NEW MOVE IN TODD FIGHT": about the death of Mrs. Margaretta Todd and "Mrs. Rosalie Tousey, daughter of the dead woman". [web] https://www.loc.gov/resource/sn83030214/1905-11-06/ed-1/?sp=11&st=text . The relation to the physician is unknown (possibly a family member). The Nov 1905 cluster of hits (Montgomery, Spokane, sn82014248) probably reports the same story. It is not about the x-ray work.
Not reached: the 1897, 1899, 1902, 1903, 1914 and 1919 hits. Of these, the 1897-1903 hits fall in his early x-ray years and are worth reading next.
