WikiTree can be an excellent community from which you can find others who are also interested in helping find answers to these kinds of questions. I recently read an excellent article in the Washington Post that describes one woman's journey to find answers in her family tree, and you may get some inspiration and ideas from it:
https://www.washingtonpost.com/graphics/2017/lifestyle/she-thought-she-was-irish-until-a-dna-test-opened-a-100-year-old-mystery/
I also suggest making sure to utilize the tools available at the GEDmatch website, where you can start doing some investigative research to find others whose DNA matches yours, and email some whose DNA seems like the closest fit.
And be sure to post further follow-up questions here at WikiTree when you make progress, but hit various 'brick walls,' and you may find someone who has just the tip, clue or answer you need.
Good luck!
