1911 Bible Students Convention in today. It has several pictures of various Bible Students of the day. I came across this one of Malcolm Rutherford (son of J.F. Rutherford). It's while Russell was still alive and apparently Malcolm was deeply involved with the Bible Students at the time. He is listed as Pastor Russell's stenographer.
"The Proclaimers book quotes Mary's obituary in the local Monrovia Daily News-Post newspaper which notes her "poor health" as well as her active involvement with the JWs, so there may be an indication that she remained with Rutherford's group at least for some time. RR suggests that Malcolm split from Rutherford soon after his takeover of the Society. It is interesting tho that in 1920 Malcolm worked as an attorney in Los Angeles before becoming a clerk at Superior Court" ~~~~ Leolaia
