Well, this query very dated at about 12 years old, but since no one has responded I'll leave a short note for future reference.
Bethany's father was Daniel Veist Van Syckle, and her mother was Susan Bird. All three of them were born in New Jersey. Dad and Mom died in Newaygo county, Michigan, but Bethany moved to Oregon in her later years with one of her children, and Oregon is where she died.
Bethany originally married Thomas Sutherland, about 1848, and they had several children together. She would later marry Thomas' younger brother, Solomon Sutherland Jr., about 1866, but had no children that I'm aware of in that union. Of course Solomon Sutherland Sr. was her father-in-law for both marriages, and is probably where you get that name.
Bethany Van Syckle was born 27 Nov 1829 in New Jersey, and died 25 Mar 1920 in Oregon. She lived about 90 years.
Footnote: There are many different spellings for this name. The spelling I use is directly from the Daniel Veist Van Syckle headstone.
