The BC Archives Genealogical Vital Events index lists a baptism for an Eldred John Yule in Okanagan Landing:
Event Place:
OKANAGAN LANDING
Father Name:
JOSEPH BROWNING
They have it available at the archives in Victoria, but that's all I could get online. Depending on his religion, you may want to contact The Spallumcheen Methodist Mission fonds to see if they have anything on record.
I was also able to find him in several censuses in the USA using Family Search:
