Based on just one site, I collected the names of Jews who were killed by Arabs between 1873 and the Fall of Tel Chai in March 1920. They were either civilians going about their regular business or guardsmen protecting Jewish property and life from Arab attacks.
I used the official Yizkor site which itself is based on books, memoirs, archives and newspapers. It seems there is another, different, counting in this book, page 205 (which just had its 25th anniversary celebrated. He's not pro-Zionist).
The dates I selected are arbitrary. I actually consider Avraham Shlomo Zalman Zoref, who was murdered by sword blows in 1851 as the first Jewish victim of Arab terror intended to deny Jews our national rights. I have not yet located a site to find names from 1851 to 1873. The list should be considered incomplete.
* Yosef Sussman, for example, was walking back to Jerusalem from his duties at Qalandia when he was killed, his body, presumably tossed into a cave or cistern, never found.
Let us not have new terror victims cause us to forget those who were killed previously.
