Kate's family history - contrary to her now relatively opulent lifestyle - is one that many of us can attest to in our family trees.
Kate's family are from the North of England and - up to the last few generations - her ancestors were mostly working-class. According to the New England Historic Genealogical Society her ancestors include merchants, messengers, solicitors, cabinet makers, butchers, bakers, a laundress, and coalminers.
The Society also revealed in November 2010 that Kate Middleton (along with the Queen Mother and Princess Diana) is a cousin of America's first president, George Washington.
