One of the first things of interest about Casimir is his last name. It is unclear if he was born with the name Bruynell or Bruyneel. My father-in-law, Ken Bruynell, says the last name was Bruynell when he arrived here from Belgium, but due to Casimir's inability to speak clear English whomever the customs officer was either spelled his name incorrectly or one of the "L"s in Bruynell was written small and it was interpreted as a small "e" and therefore the name became Bruyneel.
Shortly after his arrival here is the U.S., he had to marry and underaged Emelie A. VanCouwenberghe and they had one child, Oscar Bruyneel, together in 1905. Like many Belgian men of that error, he was a cigar maker. We are not sure what transpired, however before Oscar turned 5 years old Casimir had moved on.
In looking at border crossing records it seemed that Casimir made many trips to Canada. He then married Theresa Mary Batsleer and they had one child together in 1912.

He died on December 30, 1947, in Goffstown, New Hampshire, at the age of 65.
Note: If I could have just one conversation with Casimir, I would ask about his family, did he have siblings? Would he tell me why he decided to leave his first family? Did he arrive in New York or in Boston when he first came from Belgium? What was going on in Toronto? Do we have unknown family up there?
