David, Saw your message on the Genealogy message board regarding your Parvin ancestors.
You mention that your family came from London, but I believe your earlier ancestors may have come from Yorkshire and belong to the same tree as myself, your great grandfather George John being born in Sheffield, moving to London where he married Alice Taylor Rowland and raised a family, George L., Alice R., Katherine May, Mirriam Lucy B., Edith and Winifred Elsie.
George L. being born in 1890 at Hornsey and marrying in 1913 in the Greenwich Reg. Dist. to a lady with the surname of Hills.
Does this sound like I have the right family?If so I would be pleased to hear from you with a view to exchanging information.I can take this tree back to the 1600s, having been researching the name for the past 5 or 6 years.
