Dolly Hewitt was the daughter of Samuel and Gertie Hewitt and twin sister of Molly. Dolly had five brothers and sisters from Samuel's previous marriage to her namesake, Dolly, who was Gertie's older sister. The Hewitt clan was among the worst hit by the Weatherfield TB epidemic; Samuel never lived to see the birth of the twins and Dolly lived for just three months. Dolly first appeared in Daran Little and Bill Hill's "Weatherfield Life", published in 1992. Other information is derived from Little's follow-up book, "Around the Coronation Street Houses".
