Our archivist has done some research into Chantrell and discovered the following information
1. George Frederik Chantrell, 1873, 6 Hatton Garden Liverpool. Patent for new and improved filtering and deodorising medium.
2. 1864 London Gazette notice re. partnership dealing with marble, cement tiles, chimney pieces, terra cotta ware, plaster, lime, grates.
3. 1876 London Gazette noted as Sanitary Engineers.
4. 1884 London Gazette noted as debtor and Building Material Merchants.
The cemetery was built in 1837, some years before these dates, we are not sure whether this indicates that these pieces came from a later build of some sort. Or are they part of a drainage system of some sort, introduced into the cemetery later - given the mention of sanitary engineering above.
Can you help solve this interesting mystery?
