Don, since posting the above message have you been able to learn anything about your Catherine Joyce?
I'm wondering if you know anything about her parents/sibblings. You said she lived in Milton MA?
I know of a Ella V Joyce who married a Doyle, and lived in the Northampton area of MA and had 4 sons, one was Bernard, who became a doctor and died in San Franciso in 1990. I believe there was a Raymond, and two others I've forgotten.
