Happy Easter Sarah, Kate and Anne,
I cannot offer enough thanks to my friend who kindly recommended a lovely book by Máirín Johnston "Around the Banks of Pimlico" published by Attic Press. I spotted your enquiry about Christine Moore. I imagine Moore was probably a popular name in the Coombe area of Dublin. I have been browsing through and dipping into my book.
I noticed the name Catherine Moore. Catherine, in the late 1850s, was employed (with no testimonials) to teach sewing at the Catholic Ragged School in Park Street West.
All the Best, Chris
