I found a half brother of Philip, Donald and myself in our family tree and I believe this represents a mistake. Neither the date and location of his birth, nor of his death , nor his mother's name are indicated.
Should anybody be in the position to provide Donald and myself with any information on the existance of Isaac, he is more than welcome to do so.
In absence of any information, I shall remove Issac's name from our family tree in due course.
