USA death details for Christina b. 1855 who looks to have married Rollin Waller (I thought this name didn't sound very Scottish

WALLER, Christina (Fraser) 88y 9m 10d (

pretty precise given her birth shows on 05 MAR 1855 in Kirkhill), 15 Dec 1935 m. Rollin Waller, and
WALLER, Rollin T., 31 May 1928
http://genealogytrails.com/ill/whiteside/cemgrovehillw-z.htmlThis looks to be Rollin T Waller on the 1880 US census - the only one with such a name, quite an achievement given the population!:
Rollin T. WALLER, 44, farm hand, b. IL
Martha J. WALLER, wife, 42, b. VT
Address: Durand, Winnebago, Illinois
The 1910 US census shows:
Rollin T Waller, 75, retired b. Virginia Illinois
Christina Waller, 59, b. Scots Gaelic
Census place: Durand, Winnebago, IL
Rollin and Christina look to have been married 11 years, no children.
The big health warning on these details comes from the 1900 US census, where Christina F Waller shows as born in Nova Scotia Canada
