Here is the 1881 for the Brown's living in St. Lazare Que. It would appear that Jeremiah Brown age 20 and his wife Lia Amiote age 18 are living with his parent's Jeremiah Brown age 87 and Philomine Proula age 42 plus 3 younger siblings.
It states that Jeremiah Sr. was born in England. On his death certificate Ireland was written down after scratching out Scotland. He probably was from one of those British Isles. There is a great age discrepancy between Jeremiah and Philomena but nothing would surprise me. It does like there was a correction on his age but it hard to tell for sure what it is.
Philomine's maiden name stated as Proula could also be Proulx or Proule.
