Lawrence L. Hayes & Jennie Mae Duprey

I'm doing some searching on ancestry.com for more information on Lawrence L. Hayes and Jennie Mae Duprey.

One thing I've noticed is that the Hayes family seems to have stayed in Chittenden County, Vermont for a majority of the time.

I'm trying to figure out if James Edward Hayes was counted twice in the 1920 census.

1920 - Williston, Chittenden County, Vermont
dated: January 7, 8, 9, 1920

HAYS, Margaret E. - HEAD - 64
HAYS, James - Nephew - 17

1920 - Shelburne, Chittenden County, Vermont
dated: February 5, 6, 7, 9, 10, 11, 1920

HAYES, Lawrence L. - HEAD - 60
HAYES, Jennie M. - Wife - 44
HAYES, John W. - Son - 28
HAYES, Thomas L. - Son - 24
HAYES, William R. - Son - 20
HAYES, James E. - Son - 18
HAYES, Stephen R. - Son - 15 -
HAYES, Ruth M. - Daughter - 10 -
CILBRITH, Ethel M. - Granddaughter - 1 6/12
COCKLE, Charles - Uncle - 66

I'm thinking James moved back into his parents' home after January's census but before February's census. I'll have to scrape together the censuses that shows how Margaret is sister to Lawrence.
