You MIGHT be able to contact the funeral home for additional information, if you can prove you are related. They might refuse due to privacy issues, though.

According to public records, he lived with:

Valerie Carey
Anne Marie Carey (may be Anne Marie Bacowsky)
Kevin A. Carey

Records do not indicate WHEN he was living with them -- It could have been years ago.

Do these names ring a bell? Are you looking for them?
