Hi, I just visited the Halls Ferry Cemetery in Marion County, Oregon. I also looked online at find a grave for this site.
I noted on the (online) list of internments, that an infant child of George Bogosian (b. Armenia) and Mildred Louise Croshaw Bogosian (name of Robert Earl Bogosian) is there (born and died in 1928)
As I am sure you know, as this is your family line, Louise's sister (Laura Arlene Croshaw) married Armenian born "Mike" Parsegian. In the same cemetery, Halls Ferry, an infant child of theirs is interred there (June 23, 1922 to October 19, 1922).
Do you have any idea about how it happened that Armenians immigrated to the Willamette Valley, Oregon? And two fellows married sisters of the same family??
