Sephardic Naming Patterns
When considering whether Isaac (The Blacksmith) named his children in any particular pattern, it is worth examining how the Sephardic community named their children.
There is an interesting article in the Transactions of the Jewish Historical Society of England (JHSE) written by Edgar R Samuel "New Light on the Selection of Jewish Children's Names". These naming patterns are generally fixed although there are a couple of rule exceptions. The main rules are:
From the tree we can see that Isaac's known children are:
If "our" Isaac is the son of Jorge Alonso or George (or Isaac) and the great grandson of Abraham (Antonio) we would have expected to see:
NOTE: Of course the 'Chrisum' Child, died at birth and is given this name in the registers. A Chrison child died before its Mother was churched. The name comes from the "Chrison" shroud placed around the baby after birth and delivered to the Church for its ablutions after the Baptism/Christening. A Chrison Child was often buried in this shroud.
Conclusions (if any)
This does not look quite how we would expect it to be if Isaac was naming children in a Sephardic pattern, although we believe he hardly could have known his father (if any assertion about his father being Isaac/Jorge/George being correct) and so may not have had the necessary information/tradition handed down to him.
So what can we conclude? I do not think we can add, with certainty, that Isaac used a naming pattern as detailed in the rules above. What we can see is definite Sephardic names and perhaps the possibility that some are named after the Grandfather and Father of Isaac, if this link is ever proven. It does not get us much further but adds an extra dimension when considering who Isaac's father may be.
