This is a very unusual variant name of old English origins which appears to originate in the same area as the town of Cinderford in Gloucester and therein lies the clues. The derivation is from the term "Sinder" and refers to a medieval maker of charcoal, or to one who was responsible for collecting the manufactured "Sinder". The name is also found as Cindler, Cinderry, Sindrey, Syndery, Sindry etc.. The recordings include Guy Syndery christened at Dymock, Gloucester on April 25th 1630, whilst on January 6th 1756 Betty Sinderey married Edward Bown at Ampney Crucis. On December 29th 1801 Thomas Cindry married Ann Butt at English Bicknor and this may be the first use of "c" instead of "s", whilst on October 6th 1859, Charlotte Cinderey married Thomas Barnes Bloss at Woodchester, Gloucester. The first recorded spelling of the family name is shown to be that of William Syndrey, which was dated August 9th 1618, christened at Sherborne, Gloucester, during the reign of King James 1, of England and V1 of Scotland, 1603 - 1625. Surnames became necessary when governments introduced personal taxation. In England this was known as Poll Tax. Throughout the centuries, surnames in every country have continued to "develop" often leading to astonishing variants of the original spelling.
