I think that should be Sherrard Avenue.... unfortunatly like a number of minor streets without businesses, Thom's 1904 doesn't include a detailed listing, just the following :
Sherrard Avenue
off Sherrard street Lwr
40 small houses
same details appear in 1906.
The house numbers appear to be consistent on the 1911 and 1901 returns as some of the same families appear at the same addresses (e.g. O'Shaughnessy, Levery), and by 1911 the occupant of No. 30 is an Anthony Duke.
