[MargaretR]

My fraternal grandmother was Margaret Amelia Marsden (see pic)
She had 2 sisters - Lily and Elsie.
She married Benjamin Rothwell and they lived at 15 Stanley St Oswaldtwistle.
She died in the late 40s when I was still a child. I know little about her background except that her father was a schoolmaster and a lay preacher, at Immanuel school Oswaldtwistle
