I did a Google search this morning for Ohlegschlager and found this.
This would be a mail-list at rootsweb.com for Sherman County OR.

Polk’s Sherman County Tax List 1910
Ohlegschlager J F, $1195, Kent.
Kent is along highway 97 a bit north of Shaniko. By 1910 Jacob was deceased, Jacob J was in The Dalles. Could this be John, the oldest of the Ohlegschlager children? I checked the census indexes for 1910 but have not yet found this person.
P.S. The Ohlegschlager BLOG also came up in the search (which is why I was Googling)
