Hello from France.
I had difficulty with Millisle information,-I lived there as a child and could not find any real info-regarding my paternal family.
I at that time lived in one of the cottages on the beach!!next door but one to Church!!
I contacted Millisle Forum,and was so fortunate to have a Katie Boyle contact me,and very kindly searched the small churchyard-contacted church to see what type of records etc.
As it turned out--Katies elderly grandmother -who owned the farm closeby had some memories,and was able to help me.
Two years ago --I too revisited Millisle, and was made so welcome by Katie Boyle-(must mention she is responsible for the lovely tourist info magazine).
Do try to contact her-and very good Luck.
