Julian was indeed the older brother of Edgar Walter Fripp. They were two of, at least, 11 children of John Edwin Fripp and Isabella Jenkins. Another sibling was Robert Lee Fripp born about 1872 (according to 1880 census). I don't know if this is the Robert you refer to. You can see the full entry on the LDS Family Search Website.
I am slightly confused by your previous message as you say that Sidney Benton married Anna Ellis but your latter message gives her name as Rosa.
