From Mayflower History Website, http://www.mayflowerhistory.com by Caleb H. Johnson:
Joan Hurst was born in 1567/8 in Henlow, Bedford, England, the daughter of William and Rose Hurst. She married first to Thomas Rogers in 1593 (not related to the Mayflower passenger Thomas Rogers). With her husband Thomas, she had a daughter Joan, baptized on 26 May 1594 in Henlow. When Thomas died, around 1594 or thereabouts, she remarried to John Tilly in 1596.
John and Joan (Hurst)(Rogers) Tilley came on the Mayflower in 1620, bringing with them daughter Elizabeth. Joan, along with her husband, died the first winter at Plymouth, orphaning their 13-year old daughter Elizabeth in the New World. Elizabeth would later marry to Mayflower passenger John Howland
