if the eldest was born in 1916, it's unlikely the family would be on the 1901 census. Do you have birth certificates for any of the children or the parents' marriage certificate? We might be able to find parents' families given the fathers' names and occupations from the marriage certificate.
The only possible marriage for a David Morgan to an Emily in the area on FreeBmd is
David Morgan june qtr 1908 Llanelly vol 11a pg 1948 with Emily White on the same page. But an eight year gap between marriage and the first child, when they were several children, doesn't seem very likely. Coverage of marriages on FreeBmd isn't complete from 1911 - 1915 and just about non-existent from 1916 onwards, so marriage is quite likely within this period. Registration district should be Llanelly for Llanedy at that time. If you don't have certificate, you'll need to search the full GRO index which is free on Ancestry.
