Hi
it looks like your family are after the 1901 census
you will need to look up the 1911 census for more info we are unable to give you info because of copy right laws
I have found the following on
http://freebmd.org.ukJack Edmund Watts 1909 1st qtr vol 11a page 691 pontypridd
Marshall E H watts 2nd qtr vol 11a page 1210 mothers name Hill pontypridd
can only see one marriage thats if they married in Glamorgan
William Watts =m= Sarah hill 1901 vol 11a page 765 2nd qtr cardiff
hope this is of some help
cheers cardiff
