Hi Frances, Richard and Sue
I sort of still think this Isabella may be of interest.
I am still checking the 8 Isabella's who married into the Quirk/Quark family 1818-1841 , plus another one in 1850 for the period 1841-1851.
I tried to find Isabella aged 42 in 1851 on the 1841 census. Remembering that ages are notoriously wrong, so looked for anyone aged 25 to 39 in 1841.
Found 2 aged 25-29 in Conchan and German and 2 aged 35-39 in Marown and Lonan, but I found the four on the 1851 census.
Looking after 1851 , possible in 1861:
Bella Quirk aged 54, a widow , Water Lane, Conchan, b Douglas ( the first 3 inhabitants b Douglas , possible error), a boarder ad a mendicant ( New word for me - a Beggar) with a Clark Family.
And in 1871 not total match
Isabella Quirk aged 64, single ,Seamstress B Patrick a Boarder in Patrick with Jane Laughlin 75 Born Ireland.
Can't find any match in 1881 census, There is no suitable burial in Patrick, but one in Maughold 3/1/1878 is about right age - 71 address given as Church Street, Ramsey.
Does anyone have knowledge of any part of this posting that can verify or discount the facts
