My DNA has been tested at Family Tree,  my research says that Walter Fitz Gilbert is my grandfather approx. 20 generations ago, how can I tie my DNA to him? I am a member of the Hamilton Geneoligical Group.

Perhaps you need a Hamilton Tag as his is not a Gilbert family

His DNA has not been tested, so on FTDNA you most likely match others that also have him in their tree.

As for "matching" I am not sure if you could triangulate with others going that far back, ...........  but for triangulation to occur you need at least 2 others that come from separate lines but meet in their tree at the same person as you and then you can run your DNA data along with theirs through GEDMatch and see if you all share DNA on the same spot on the same chromosome.

Another thought....if you are waiting for his profile to show you have taken a DNA test, you will have to add all your ancestors to connect to his profile, then it will show on his profile that " It is likely that these DNA test-takers will share DNA with X".

Which DNA Test did you have done? If auDNA was done there is very little chance that you will find a connection because an auDNA test will only show results for about 6-10 Generations. Most GG (Genetic Genealogists) will tell you to expect nothing much past your 64, 4th Great Grands.

If you did a Y-DNA test, then you will be able to use this information along with your paper trail to compare to others who share specific mutations along your line and their line back in time. Your Surname doesn't look like Fitz Gilbert - Hamilton, which makes me ask, Are you a direct, Male Line, descendant of Walter? If so, and your surname was changed at some point from Fitz Gilbert to Hamilton, you will need to do the research to find this change. A Y-DNA test is ONLY for the direct male line, so your fathers fathers fathers father...
