One thing, the Artillery record does indeed show that Thomas re-enlisted 18.7.21, age 30 yrs 6 months.
It looks to me that it might have been then that Vera's birth was written up, along with the son born 4.2.21, and with another child born 1922 later squeezed in between them (in pencil)
Possible that Vera was adopted?
Occupation of Thomas on his original attestation was Cycle Polisher, confirming that he is the chap in Ireland in 1911 (they very kindly give their pre army occupations in the census)
