Hi Cathayb
thanks for your reply. The marriage and death records for James Manley do not list parents. But given that Eliza and a James had what look like to be the same parents, William was a sweep, as was James who was transported (Parish listed as Bridport), they are my best bet for a family unit. I can't find any info for Eliza after the court case and can only find a ticket of leave for Thomas Eglinton. A bit more circumstantial evidence is that James' children included a William and Sarah (though given how many people were called by these names - it certainly isn't conclusive!).
Thanks again.
take care.
