Jean,
I have always copied down any info. I found about the McCarthy's in case there was a link with my family. There are so many different spellings of surnames aren't there? Your Mary for instance is on Brian Lawson's 'Dissenter Baptisms' as Mary Coaty.
I have found a burial at Braddan of Alice Hoy aged 87yrs 15 Oct 1882 grave2842. I haven't had time to get copies of the wills yet. Marie
