Sorry I can't remember offhand but there is a card index in the Museum Library.

There is some info of my late 5th cousin J.A. Brew about this family on the web. Enter the words crebbin plus will plus Paul plus charles in a well-known search engine....

If this doesn't find it, try Brew Ballavarran plus crebbin.

Use the plus sign not the word.

I would run a check over Alfred's material, but it is likely to be pretty sound.
