I have posted sourcing on Martin, the ancestor of a particular male line of Martins which is currently being called a "Tours" family for many generations, all based on a very old and rejected idea that Martin (and never this descendants) was "of Tours".
I propose that for reasons now explained on the profile, Tours (and anything like it, such as de Tours) should be removed from ALL surname fields for him and his descendants.
Martin himself really seems to need to be "Unknown" as LNAB.
His son Robert (whose brothers are another problem) was a FitzMartin in reality, and it seems his son William fitz Robert fitz Martin sometimes slipped into using fitz Martin. The next two generations William and Nicholas were more consistently Fitz Martins, so it was now a surname. After that it seems to have started slipping into just Martin.
So the family is a FitzMartin or Martin family. I would prefer that for this early family where we currently have Tours or Torres or whatever, we use FitzMartin.
Does anyone see a problem with the proposal?
