Forum:Rebecca and Lowen name origins

I have made some research into the names of Rebecca and Lowen and I wonder if my results in any way can be related to their naming in Fire Emblem: Blazing Sword.

Rebecca

There is a Rebecca mentioned in the Book of Genesis where she was the wife of Isaac. With this as the background we go to the novel (fictional) Ivanhoe written by Sir Walter Scott where a Jewish healer name Rebecca is featured, in the book she is the daughter of the Jewish merchant Isaac of York.

So her name can either point to her place in the Book of Genesis, or the Rebecca from Ivanhoe who is a derivative of the Rebecca in the Book fo Genesis. Or it can be neither since Rebecca is a common female name in the western world.

Note: In the Japanese version of the game Rebecca was spelled Rebacca.

Lowen

This thesis is very far fetched, just so you know.

Rowena is a name that appears in two British works of litterature:

1. Historia Regum Britanniae by Geoffrey of Monmouth is the source of the Arthurian legends and in them there is a woman named Rowena who is the Anglo-Saxon leader Hengest daughter and wife of the the Briton King Vortigern.

2. In Ivanhoe written by Sir Walter Scott a woman named Rowena is featured as a beautiful Saxon heroine.

Now to my point.

In Japansese, as far as I know, R and L are interchangeable. With that we can make Rowena to Lowena, then from Lowena to Lowen there is not a long step.

Conclusion

Both Rebecca and Lowen can be traced back to the work of Sir Walter Scott and the litterary Piece Ivahoe, the first easier then the second. Both characters are also related in the game so it is not impossible that they have names from a shared source. Please give your opinions on my thesis.
