Cremation destroys the DNA except in remaining bones and teeth which are pulverized and mixed into the ash remains. There is a very slim chance to gather any DNA info - check this out:

Why are you interested in DNA from a distant relative? What are you hoping to determine? Do they have multiple living children? You can usually gain most of the DNA information from parents if you can test three or more of their children. Testing the children of this relative would prove to be cheaper than using an alternative type of test for DNA that had little chance of success.

That was an interesting comment "You can usually gain most of the DNA information from parents if you can test three or more of their children." I hadn't thought of it this way, but it makes sense. Do you know of any studies or statistics on this?

Right off the bat tonight, I can't. A similar concept is talked about here: https://dna-explained.com/2015/01/14/lazarus-putting-humpty-dumpty-back-together-again/
I have created Lazarus kits before. They are an interesting concept. It would be interesting to compare the final result with a kit that was for an actual person. I will have to think about it and see if I now have DNA where I could do this. I might have close to enough DNA to make a comparison. Not tonight though.

I work with matches more than chromosome segment triangulation. Here are the results of looking at myself and my two siblings. At Gedmatch, I start with myself and find my top 2,000 matches. If I compare, my sibling's top 2,000 matches with mine, I find that together we have 3,134 unique matches. If I look at all three of us, then we have 4,011 unique matches. The statistics show that one sibling captures on average about 50% of one parent's atDNA. If you look at two siblings together, they will capture 75% of one parent's atDNA. With three, the average is 87.5%. Now these are averages and they could vary for specific cases. Thus, if you tested one parent and siblings, this is what you would expect to find for your grandparents.
