Yes and no to answer your question. I am a facilitator at our local genealogy group here in Homer Alaska. I posted for one of our members who is researching information about your dad and the propeller for a story he is researching about how the propeller came to be here. We found your mom's name on a census report and he got the address online. We did not know your mom was deceased. I believe then your brother received the letter he mailed to the address. Thanks for any help you might be able to provide us with.
