Ellen was baptized in Blackburn on 21 Jul 1821 by William and Mary FORREST of Samlesbury. No baptisms were conducted in Samlesbury between 15 Jul and Sep 16 1821, perhaps the church or minister were unavailable.
Ellen's mother died in 1826 shortly after her sister Ann was baptized in Samlesbury by Wiliam and Mary FORREST of Mellor. Her father remarried, to Nancy ELLISON in 1832, however her step-mother also died in 1838, and the family appeared to have broken up.
In 1841 she was living in 'club houses' on Mellor Lane, the main East-West road through Mellor. She and the family she was staying with were all described as cotton weavers. Club houses were built by subscription to a building club, so the place name was likely a reference to a set of newly built cottages, possibly with weaving shops forming an integral part of the design.
Her father was living alone in Blackburn, and her younger sister, Ann, and half-brother James, were living with relatives - possibly their grandfather and uncle) - at Wagtail, Duke's Brow.
It's unclear what happened to Ellen after 1841. She probably married, although who, when and where they were living in 1851 is unknown. By then hand looms were being out-competed by power-looms and factories, and the Mellor population was moving away.
In 1851, several of the families in the 'club houses' were in Blackburn, including some close neighbours who were giving lodgings to Ellen's half-brother James. It's possible that she was in contact with James, had made the introduction to the lodgings, but being married was elsewhere in 1851.
