Wikitree only adds DNA to 5 generations back (and out to 3rd cousins) and if the person you are looking at is more than 4 generations back from you, or a 4th cousin, then NO it will not show up.
DNA is only certain (accurate) going back 4 or 5 generations,. Beyond that the connection becomes very uncertain (inaccurate or hit & miss)
As far as I can tell, all of your ancestors have a DNA connection to you.
It might help if you gave the link of the person you are trying to connect to.
