I'm not positive that this is Ellen's spouse, but considering the neighborhood, I think it might be. See note at end.

NOTE -- The 1880 census lists Oliver's wife as Helen, which is probably a corruption of Ellen, however, it also shows her place of birth as NY whereas we know Ellen Foster, daughter of Ebenezer Foster was born in Cuyahoga County, Ohio. Thus I've come to the conclusion that Oliver may have married an Ellen Foster, but it doesn't seem likely that she's the daughter of Ebenezer.
