Martha Derricott was born at Rockwordine-wood, Shrop, England May 24, 1824; her parents where Charles and Mary (Ashley) Derricott. Martha's daughter, Elizabeth, was born in 1854. Elizabeth's father appears to be Richard Manwin but the history does not specify if Martha and Richard were ever married; it only says that for some reason the two were separated. Martha immigrated to America with her husband William Tonks in the summer of 1856. When they left her daughter, Elizabeth, stayed behind with Martha's parents. Martha and William traveled in a small ship for six weeks, finally landing in New York City. They eventually continued on to Salt Lake City; first by boat to New Orleans, then up the Mississippi River to Council Bluffs, finally arriving by wagon train in Salt Lake City, Utah October 1, 1859. After arriving in Salt Lake they only had time to construct a small log cabin for their family and they lived the entire first winter with only half a roof on the building. They later moved to Morgan City, Utah where her husband William worked as a blacksmith. Eventually Martha's parents and her daughter Elizabeth came and joined her family in Utah. Martha passed away on September 14, 1911.
Folder 5 of the Tonks Family collection is the one which contains biographical information relating to Martha Derricott Tonks. The folder holds short biographies for many members of the Tonks family. Martha's portion is a one page biography under her name and information under the name Edna Sheets Hansen (Martha's granddaughter), who describes her grandparent's journey to join the saints in Zion. Information can also be found in almost all of the histories included in the collection, as many of them include stories of Martha's pioneer trek across the plains. One time during the journey Martha became so tired she laid down a ways from the trail and fell asleep. Upon waking she found that the wagon train had moved on without her. She ran to catch up with the party but soon came to a river. She was then given the aid of a group of men on horse back who took her across the river and she joined her party. For her whole life Martha remained true to the Gospel message that she received in her home country of England.
