What age they record at her death is not really important.You have ID'd her parents and siblings and have their marriage/birth certs, correct?Daniel is her brother?And, of course she can be born in 1864 and her parents married the same year - they married Feb, she was born NOV - 9 months.
So, there is a Jude/Judy/Julia 27 Nov 1864 ...
Very very common to have (sometimes 10 yrs) inaccurate dates of birth recorded.
So, you are getting closer and closer in age ... now, there is the possibility that Tim/Cath had another daughter of the same name that died and they used the name again ... that does happen.
