Membership was about 650 in 1855 when Keil, fearing Bethel too subject to outside influence, led a group west and established Aurora Colony in Oregon. Their expedition over the Oregon Trail is unique for it was conducted as a funeral cortege. Keil’s son, Willie, died before he realized his father’s promise to lead the group and was carried instead in the head wagon in a metal box, alcohol-filled. After six months and over 2000 miles, he was buried at Willapa, Washington.
Keil never returned to Bethel, directing affairs there by letter. When the colonies disbanded, 1879-1881, they held property in common valued at $109,806. Bethel supplied $64,328 of this and owned 4267 acres.
