census is probably the way to go and this one in 1901 looks likely:
1901:mouldsworth,cheshire (near to Birkenhead)
William Evans 48 railway signalman shropshire, snailbeach
Sarah M Evans 43 shrewsbury
Sarah A Evans 16 Horton,cheshire
Ethel W Evans 13 warrington,lancs
Ernest J Evans 10 new brighton,cheshire
Thomas A Evans 8 Mouldsworth
John E Evans 7 "
Catharine G Evans 5
Percy H Evans 2
Alfred H Evans 4 Months
do you know if Thomas had a middle name? do you have the marriage /death certs?
