Arthurk, thanks yes now iv'e changed the burial/death dates on the new memorial. Oh yes just found the probate record I wonder who Tom Hall was ?
£1.50 for a pdf copy of the will, and it would probably make it clear - but as the will was proved in London, make sure you include the handwritten folio number as part of the order, otherwise it will be rejected.
Meanwhile, the 1901 census has a Tom Hall, mineral water manufacturer, age 47, born in Huddersfield, living in Heanor, DBY, with his wife Lily L and 3 month old son (also Tom). There's a possible birth for the son in the Basford Reg Dist in Mar qtr 1901 with mmn Smith, and that seems to be corroborated by a marriage between Tom Hall and Lily Louisa Smith in the Huddersfield district in Sep qtr 1900 - also confirmed by a notice in the Huddersfield Daily Chronicle of 1 Sep 1900, and possibly other papers too.
So, who was Tom? Probably too old to be Grace's grandson, but maybe a nephew. Or maybe he'd previously been married to Grace's daughter but she had died? (A Tom Hall married a Mary Rebecca Haigh in Meltham in 1888, but I've no idea if this is relevant.) Or maybe just a good friend?
