Trip back to Liverpool a few days later than planned but got there in the end.
Sadly the records for St Richards and St Alexanders have apparently not survived or are available at Liverpool Archive Library see attached list - only those Churches with an Asterisk have Records held in the Archive Library.
As stated even RC religion had Baptisms at C Of E or even Both and not always area on residence, often the most fashionable Churches of the time in the belief that this increased the child's chance of survival.
I checked St. Albans RC and St Mary's Kirkdale COE and St Peter's COE Church St also for weeks after sadly no luck.
Baptisms could be years later or even not at all.
Tried Gores Directory but only half the street the odds listed presume the half in Bootle over the Boundary and held in Crosby Library.
Did find Elizabeth Dalzell Birth Dec 1912 West Derby Vol 8b page 806 Mother Casson
and 1939 Register at 202 Fernhill Rd Bootle when she Married an Owen Kelly Sep 1937 Bootle Vol 8b page 37
Is there a reason why you want the Baptism Record ?
Do you need any other help re her life ?
