As an only child, married to an only child, I inherited everything from my DM, and all the 'girly' things from my DMiL.
I have an abundance of tea/coffee sets; dinner services; lead crystal bowls, vases and dishes; and a lot of good jewellery. My MiL got a new engagement ring 3 years before she died, it's from Tiffany's and is beautiful. I occasionally wear it on my right hand, as even though it's a stunner, I wear my own engagement ring all the time.
After my mum died and I was sorting through her wardrobes, at the very back of a top shelf I found a Cuban cigar, still fully wrapped. It was one of my dad's, he'd died 22 years previously and I wept buckets when I found it! It's now in a Whitefriars vase in a mahogany display cabinet, both inherited from mum, there's no way I can ever part with it.
I also have my grandad's medals, 'dog tags', and his 'oak leaf cluster' and the letter announcing his award. They mean a lot as Grandy and I were very close.
