I absolutely think there is a resonance about where our DNA has derived from. My first job in London I found myself working for a predominantly Jewish firm, having not really met any Jewish people before, I found myself being quite fascinated by the religion and their customs, I remember telling my mother and she felt much the same. Years later when I first started on my genealogy quest at mum's behest to find out where in Ireland my maternal grandmother's people hailed from, having done that, I said to mum "what about granddad's side?", mum had a French surname and her grandfather was French, they proved to be quite elusive but we found out through her cousin they originally came from Alsace. Later on I was contacted by a third cousin on Ancestry and she told me the family was Jewish, and my maternal grandfather was half Jewish, but we certainly didn't know that, only that he wasn't a catholic like my grandmother. Unfortunately I only found out that after my mother had died, she would have loved to have known that she had some Jewish DNA I suspect and quite surprised I imagine,.
My paternal grandfather came from Malta, and his line includes both Sicilian and some strands of Anatolia and The Caucuses, such a big area though! who came from there I wonder? Although Malta has it's own official language which has a certain amount of Arabic in it's make up, when my grandfather was born at the end of the 19th century, Italian was the official language and I applied for his birth certificate I was really pleased to see it was all in Italian, Italy is somewhere I've always been drawn to.
