Jaqueline would be my age or maybe a year younger. She was going steady at school, so ‘off limits’ and I don’t know her history at all. She would have lost her name on marriage, but *if* she had a much younger brother then the timescales would allow him to be your son’s fiancée’s dad. Very tenuous link, but would be easy to check this one. Best wishes to them both in any case. Cheers Andrew.
