Has any one ever heard about this individual? Charles François Hyacinthe Sérant, he was imprisoned in Cayenne in 1899 and escaped on August 11th, 1903. He has the same last name as my grandfather's mother and she also lived in Cayenne up until her death. I am wondering if they could have been related. I am still trying to find where my grandfather's sister who was called Milly Sérant, could have gone to when she sailed out of Cayenne just after WWI.
