My father's family was Finnish...he spoke Finnish before English, but swore to me that he didn't remember a word of the former by the time I came around.
This reminds me of a letter I found, sent to my dad by his mother while he was away with the Army in WWII.
She told him about something dramatic that had taken place in her neighborhood that had caused injuries, maybe a fire or something like that...the following is my paraphrase.
"Unfortunately, several people were hurt.
Also some Swedes."
