My partner of 9 years died last september.?

I had to vacate his house as he left it to his daughter, I had only been living there permanately for 18 months. I struggled through on shock, finding a new home for myself and my daughter then went into a depression not just for the lost of my partner but for the way in which his family have disowned me. Now that i am somewhat recovered I want some of the things we shared together and the gifts that I bought for him. Whats the best way to approach his family as I really dread seeing them again.
