excerpted from David Tate : Origins, page 87:

3,    Wealthy William Hollinger, held a bond against land deeded for $3500, of $2000 had been paid, the balance owed from Mrs. Tate.  His half sister Mary [Maria Juzan] Hollinger, another metis, was the consort or second wife of Adam Hollinger.  William Hollinger lived with David Tate and Margaret Powell after his mother’s death.  His mother, unnamed (probably a “Grey”)

was a Margaret Tate relative.  When David Tate referred to Hollinger as his wife’s nephew, he was accurate.  Therefore, Margaret Tate was likely George Stiggins’ cousin.
And, indeed, a HOLLINGER/JUZAN.
