If we accept that Ignace was from Calabria, Italy, it is highly unlikely that his father was Paul Mare from Ardenne, France.
There is no record of a Paul Mare and Germaine Mathieu in the distribution list of 1691 or the monsterrolle of the time.
They are not in the Drakenstein membership register of 1715.
But if the source for Calabria Italy is also the unvalidated source for their wedding and Mathieu's Drakenstein death, then there isn't logic behind accepting some of the data as true (Italy birth place) and other of the data as false (marriage and wife's death in SA).
I've been trying to have a long enough pause to re-read through all our previous discusions; do forgive me if I'm missing something big.
Going off to read the Calabria birth location discussion.
The lack of SA records may be good reason to sever Germaine/ Germanine. And, as you say - the question of severing Paul Mare is then raised too.
