census, which "are the only surviving full censuses of Ireland open to the public."
This census was taken in April 1911, and includes the names of Matt Talbot and his mother, Elizabeth. Basic information about how this census was conducted is available at http://www.census.nationalarchi
Following the death of Charles Talbot, Matt's Father, in 1899, Matt and his mother lived together in one basement room at #18 Upper Rutland Street, Dublin, from 1903 until her death in 1915. Matt continued to live there alone until his death in 1925.
In viewing this next link, look to the right of the document under "Families" and then down to the eighth name under "head of household." You will find Elizabeth Talbot's name along with one other unidentified family member. That other family member is Matt.
Besides the Talbot's you will see that there were five other families totally 16 persons who lived in one or two rooms per family at this address.

This link provides handwritten information about the Talbot's. You will note that Matthew is spelled with only one "t." Under "Education," "read and write" is filled in for Matt and "neither" is listed for his mother. Two other categories indicate that both are Roman Catholic and Matt a "labourer."(A separate document from this census indicates that all families living at this address were Roman Catholic.)
