...I stumbled across this thread as I live in Chorley. 99 Brooke Street - as mentioned as the address when they left for Australia, has long since been demolished. However, where the family lived on the 1911 census (13 Southport Terrace) is still there, as is the properly John Collinson lived at in 1901 (80 Bolton Road). John's home on the first census he appeared in (17 Colliery Street) was demolished in the mid 1980's
