Per Patty LaPlante, some sources say she was the wife of another John Hicks.

According to The Gardiners of Narragansett by Benjamin F. Robinson, Samuel R. Robinson and Rowland R. Robinsion, 1919, p. 3:

"Some time, not far from 1640, George Gardiner married Herodias (Long) Hicks. She made the statement that she had been married to John Hicks, in London, without the knowledge of her friends, when between thirteen and fourteen years of age. Soon after coming to Rhode Island Hicks deserted her, going to New Amsterdam, or, as she expressed it, ""to the Dutch," taking with him the most of the property left to her by her mother. Her marriage to George Gardiner was rather irregular in form, to say the least, consisting in going before some friends and declaring themselves husband and wife.' As she was a Quaker, and a fanatic at that, cheerfully walking from Newport to Boston, with a young child in her arms, to receive a whipping at the post for her religious(?) beliefs, possibly she would not consent to be married after any established forms. According to her own account, George neglected her and would not provide for her numerous family. It may have been her pressing needs, and it may have been the superior attractions of John Porter, with his great wealth in lands (he being one of the original Pettaquamscutt Purchasers) and his promises to provide for her children, that awakened her religious(?) scruples about the legality of her marriage with George Gardiner. At any rate, she petitioned the General Assembly for a divorce, which was granted, thus proving the legality of her marriage.*"

p. 4:

"November 17, 1705, he, Henry, George, William and Nicholas Gardiner, and John Watson, all of Kingstown, and Mary, Joan, Tabitha, Elizabeth and Hannah Gardiner, and Rebecca Watson, their wives, sold John Potter 410 acres,-bounded partly by a branch of Point Judith Pond, for £150; said sum to be paid to Thomas Hicks, of Flushing, Long Island. (Thomas Hicks was a son of Herodias and John Hicks.) Benoni Gardiner died about 1731. His wife died January (November?) 16, 1729, at her son-inlaw. Job Sherman's, in Portsmouth, aged eighty-four years."

p. 203:

"The only date in Horod Long's petition to His Majesty's Commissioners and by them referred to Gov. Benedict Arnold, is 1640, about which time she said she came to Rhode Island, "not long after" which she parted from her husband, John Hicks, and joined George Gardiner."
