Hi - Isabella Catherine Kelly is on Brian's birth regt list as born 16 Apr 1882, regt Patrick, father Thomas KELLY, mother Elizabeth KAYE.
I see Thomas was recorded as Thomas William at another child's birth.

To see Brian's full birth regt list you need to look at his file on Ian Radcliffe's website at lawsonsiom.freevar.com/ (plus a lot of other records missing from the FHS website).

Yes, I've come across a number of records which used Elizabeth and Isabella interchangeably.

Do you know where William and Violet/Isabella were in 1911? (To see birth places given there.)

Sue
