the 1851 census definitely reads Eliza Grose + Lavina Grose as daughters + Samuel Grose as son - these correspond closely to ch of Matthew bur Marown 18490623 age 61 as recorded in marown register (+ also as noted in 1841census though nor Mary of correct age present in 41) - the Mary (widow head of household age 55) at 1 Woodburn terrace (south quay) Douglas was I think buried Marown 18641125 age 68
so something is quite strange here
