Walney Island] in Barrow in Furness, in north-east England, had many who were born in Ireland, now working in the shipbuilding industry or supportive industries.
However, I thought this was NOT my ancestor family when I first found it. In fact I scanned past it as the names didn't seem to match the tiny bit I thought I knew about my father's GILLESPIE family from England. This particular census of the neighbourhood ward of Walney [Island] in Barrow in Furness, Lancashire, showed the Gillespie family all born in Ireland. Well, that couldn't possibly be true - I "knew" that the Gillespies all came from England. I kept looking in England and found a few other possibilities but still, they were not particularly likely, I believed.
I took my list of 5 possibles and looked for them in the following Census, 1891. I eliminated 3 of the possibles because of the children's names - wrong group of names, wrong ages. That left me with only two possibilities.
And the 1911 Census cinched it. There were all the correct names for my aunts/uncles, in the correct order. This 1911 Census in Barrow in Furness showed their birthplaces also - huge clues for me to use to research further for my Grandma's family in England. I was able to find my Grandpa's father and mother in the 1911 Census, with their birthplaces in Ireland as well.
The confusion about my grandfather's name, William John. I'd always known his name as Jack, and I assumed that was a nickname for his correct first name being John. My mistake. He was going by his second name, which became a nickname, Jack. Don't know why I didn't twig to this shift in names when I first saw the 1881 Census. It was early in my genealogy searches, and clearly I was not as attuned to variants in names at that time.
In addition - this 1911 Census was written in my Grandpa's handwriting - isn't it beautiful? I've since found his signature on my Dad's birth registration as well, confirming this is indeed his handwriting.
Treasure - one finds treasure in the Census. There are so many possible clues to use for further research. The church district listed on the Censuses, place of birth for all in the household, ages, how long married, number of living children, occupations, residence at time of Census, signatures, and more.
