My sincere condolences. No greater pain than to lose a dearly beloved one. :-(
I'm sure there are people here who are willing to help you out, maybe there are even people who live close by (Amigans are all over the world).
Maybe if you could provide us with pictures, it would start to help a bit for us to indentify what you have at home. If there are any "big box" Amiga's (the 2000, 3000 or 4000) it may also help to make pictures of any hardware that is inside the machines (some hardware is pretty rare and sells for big money on eBay).
