She grew up very poor in East London in an Irish immigrant family. During the Suffragette movement she chained herself to the railings at Downing St. My mum isn't sure if she did this on her own out of inspiration or if she was part of the movement; she did have a friend who was from the 'class above' her but we don't know that much about their friendship. We don't know if she was jailed but it could be that great-nan didn't tell anyone, particularly given how cruelly the women were treated.
Later on great-nan used to go collecting for the poor in her community. If someone needed money to pay the doctor, or for rent or food or if they had a new baby, she would go out and collect money to help them - apparently she dressed very well and didn't look like she came from where she did, IYSWIM. Anyway, some boys were caught begging and they lied and siad they were doing it for great-nan, so she was arrested and brought to trial. Everyone from her community turned out to attend the trial in their best clothes, and all the children stayed off school. Not only was she acquitted, she was given a special license to collect for her community.
According to my mum she was polite to men, but didn't really acknowledge them at all and didn't talk to them very much, even though she was married with sons.
I wish I'd known her. My nan -her daughter - was very much like her I think, she was a cleaner in a big factory but got herself a degree with the OU in engineering.
