# Who was the 17th century mathematician "André Jumeau, Prior of Sainte-Croix"?

I'm reading Dickson's History on the Theory of Numbers, and find this on page 34:

"The third $$P_3$$ [that is, triperfect number], discovered by André Jumeau, Prior of Sainte-Croix", is $${P_3}^{(3)} = 523776 = 2^9 3 \cdot 11 \cdot 31$$"

I can find no biographical details of this "André Jumeau". There seems to be nothing out there.

I'd be grateful for any information about who he was.
