The connection to John and Elizabeth may not show in your ThruLines for several reasons.
ThruLines are based on connecting together Ancestry trees, both public and private. If your tree or other trees don't show the connecting generations, then ThruLines don't work. it may also take some time to "populate" your ThruLines as people add or add to their family trees.
Some of our ThruLines are taken from four or five other trees - and some of them are wrong. If someone else has the wrong person in their tree, then it creates a false ThruLine.
As for shared DNA matches, if John and Elizabeth are beyond your great-great grandparents, ie 3x great, 4x great or 5x great, and your DNA matches are less than 20cM, then Ancestry will not show them as matches. The only time I have found the less than 20cM matches being shown on Ancestry is if they have a good family tree and can link the Common Ancestor (and ThruLine).
Have you tried using the search facility on the DNA matches page - you can search for the name Grono or Mitchell in others families trees. This might bring up some matches than are very small or don't appear to be obvious.
