I am not related. A couple of good sites free, Google to find.
Familysearch record search.
1911 Irish Census [also 1901]
In search box I entered Michael Reilly,Pound St,Cavan Think it may be him in 1901 with wife Mary and some family. 1911[him and his wife] You could try other searches in 1911 for possible family who had left home. Hope this help Maureen
