Final answer:
There is no reference to Ruth's mother, who lost seven children and accused Rebecca Nurse of murder in the provided excerpts. The character sounds like Ann Putnam from 'The Crucible,' but this cannot be confirmed from the given text.
Step-by-step explanation:
The character in question, who is Ruth's mother and has lost seven children, is not found in the provided excerpts from various plays and does not correspond to a character in a known play who accuses Rebecca Nurse of murder. The character of a mother losing her children and making such an accusation is reminiscent of the character Ann Putnam from Arthur Miller's play 'The Crucible,' who accuses Rebecca Nurse of witchcraft which she conflates with murder. However, none of the excerpts contain a direct reference to this character or plot element from 'The Crucible'. It is essential to carefully review the context of the question to provide an accurate answer regarding the specific character in question.
