This is a slightly obscure request for this forum. If acceptable, I would like assistance in tracing records of manumitted slaves, or children born of masters and slaves, in London. This is a particular case in my Barrow family:There is a reference to Richard Barrow in the record of Joseph Barrow’s estate (source http://synagoguescribes.com/blog/Jewish-will-extracts-18th-19th-century/?value=360). The estate requests the Mayor London to emancipate his “colored boy” (son), with a request for the family to school and clothe Richard Barrow until he is twenty.There is additional mention of "John, Peter and William �my three black men who call themselves Barrow� to be emancipated in London."I would like to trace Richard Barrow’s story in detail, if possible John, Peter and William Barrow.Where are these records to be located in London?
