From George Washington to Donald Trump, here's a quick overview of the (sometimes surprising) genealogy of every US president in history.
The family history of powerful political figures is always interesting to delve into and they don't come more powerful than the President of the United States.
Some American presidents' family trees are widely-documented, like Barack Obama's Irish roots. Others, you may be less familiar with. Here, we've provided quickfire summaries of all 46 US presidents' family histories. Some of them may have genes you weren't expecting.
George Washington's ancestry
George Washington's great-grandfather was from Hertfordshire, England. He settled in the Colony of Virginia in 1657 after coming ashore from a shipwreck. In fact, almost all of George's Washington's direct ancestors can be traced back to England.
John Adams' ancestry
John Adams' roots also lie in England. His great-grandfather emigrated to Massachusetts from Essex in the mid-1600s.

It's thought that Thomas Jefferson was of English and Welsh descent. In later life, he wrote, "The tradition in my father's family, was that their ancestor came to this country from Wales, and from near the mountain of Snowden, the highest in Great Britain.” The Welsh connection has yet to be proved. Perhaps it was just a family story?
James Madison's ancestry
James Madison's great-grandfather, Captain Isaac Madison, migrated to Virginia from London. The Madison family put down roots in Virginia and generations of powerful landowners would culminate with James becoming the fourth president of the United States.
