There are numerous reasons why the two ladies do not appear in eith the online search or in the CDrom version, it may simply be they were not transcribed, but more than likely the section, page or entire book is missing, damaged etc.
Sadly many records have been lost due to fading ink, water damage, rising damp, rodent attack and worst of all humad vandalism where an entire page has been removed because one entry for someones ancestor was on the page.
I know this from first hand experience, when I sat browsing parish record books in Limerick, the PP sat with me and when I suggested he need not stay I got the reason why he had to remain with me, he then went on to show me where pages had been removed, also other damage.
When we search an undamaged book for an ancestor we knew had been born 1840 and was not able to find a record we were also informed that "unfortunately PP's did not always attend to the records and would forget to include them, so there is another reason that records cannot be found.
The firs unamed female on the list may have been one of the children you are missing, birth dates recorded elsewhere in the world cannot be substantiated anyway.
