Was also looking at this possible yesterday.
Name Richard Roberts
Enlistment Age 21

Enlistment Year 1901
Regiment Shropshire L . I.
Regimental Number 6826
Attestation Paper Yes
It looks like the first daughter is adopted. Not finding a birth reg, also has parents unknown in 1921. William Maurice Roberts b 1903 Birkenhead in 1911 is illegitimate, possible mother Jane. No children to couple/ Samuel in 1911. Looks like Elsie is the couples daughter, registered Mar Q 1921..so couple at least met around 1918 - 1920 so must have been same area, possibly Shropshire or Montgomeryshire.
Difficult with just one census to pin down earlier, and some things like father Richard, farm bailiff, etc don't seem to add up
