I have doubts about the link between Alexander (Elisha) and his supposed father Lourenco.
1. The only source for this is Lucien Wolf, Jews in the Canary Islands. he provides a statement, but no evidence.
2. Alexander is born in Venice, according to his marriage ban. Wold says nothing about Venice in his account of Lourenco's life.
3. Lourenco is married in 1653, Alexander in 1706. Quite a gap, not unusual, but needs explanation.
I suggest cutting the link until real evidence emerges. Thank you.
