Questions to be Answered

I found an 1841 census for Pontmorlais, Merthyr Tydfil, Wales that lists
Mary Mason age 55,
Richard Mason age 30,
Nahomi Rees age 13,
John Rees age 10
and
Maria Rees age 6.

It appears that Maria's Mother was taking care of the orphaned children. Richard, Maria's brother is also listed. William does not appear at this address so he must have been away. The census only listed the persons who had spent the night at the address- it did not note permanent residents.
