Thanks all, you've manged to find out overnight what took me about 18 months! Originally I only posted because I was looking into where she lived. What you have all detailed above is what I've got regarding her early life. Due to her going by Rose, Rosie, Roseanna and her ages not always marrying up, I was never entirely sure I was looking at the correct info, especially the workhouse details as they're somewhat sparse.
In summary I have this:
ROSE PAGETT was born on 27th April 1880 at the Union Workhouse, West Bromwich (I suspect this was actually the Birmingham workhouse) to Phoebe Pagett nee Winwood and James Pagett, a builders labourer. Rose’s name was given as Rosanna and her mother’s address was given as the workhouse.
The 1881 census shows that the family were now living at 5 Berners Street, Birmingham.
The 1891 census shows that the family were living at House 3, Court 29, Brearley Street, Birmingham.
She appears to be in the B'ham workhouse in 1901, aged 21. No occupation or birthplace given. She had a one year old son who died later in the year. I have his birth certificate but it adds no more details. As noted above, her mother Phoebe was also an inmate.
In 1911 she appears to still be in the workhouse, aged 29 which doesn't quite add up, and is listed as a laundress having been born in West Bromwich.
In Jan 1914 she gave birth to Frederick Pagett (my grandfather) at 99 Dudley Rd (I believe this is the workhouse infirmary), no named father. Her occupation is factory worker.
In Mar 1914 at Fred's baptism, she's living at 1/2 Brass Street and she lists the father as being called Frederick which I suspect is a lie.
In April 1918 she had a boy named Albert Edwin at 1 Western Road (again I believe this is the workhouse infirmary), no named father. Her address is 23 Willis or Wills St, Smethwick and her occupation is laundress. No record of baptism.
At some point she had another son called Walter (my mum told me this) but I can't find record of his birth or baptism.
I can't find Rose, Fred, Albert or Walter on the 1921 census.
After this is where it gets very complicated. At some point she became known as Price, sometimes Rose Ethell Price. I can't find record of her marrying. Freds Army service record (he joined up in Jan 1935) lists Rose as his next of kin, the details being Mrs Rose Price, 6 Washington St, Ladywood Birmingham. However, on another page on the service record, her surname and address as Price at Washington St are crossed out. Her details are now Mrs Rose Ethell Barrett, 4/221 or 4/421 New John St West, Hockley Birmingham (see later). I did find a electoral rolls from the early 1930's showing a James Thomas Price and Rose Price living at 6 Washington St, Ladywood. One of them also shows an Alice Price to be present.
In April 1938 she marries George Barrett at the Register Office in B'ham. She listed as Rosannah Price, a 55 year old widow with no given occupation living at 177B Harvington Road, Weoley Castle.
The 1939 register shows Rose/Rosanna (a laundry hand) and George to be living at 177B Harvington Road, Weoley Castle/Northfield.
On the 1947 electoral roll, George and Rosanna are at 4 bk 221.
In 1955 she was widowed and living at 5 bk 58 New John St West.
Rose Anne Barrett died in December 1967 aged 87 in the care home at Brookvale Road, Erdington.
I appreciate that looks like I've got most of her life covered but it's the era from 1914 up to 1938 that's a real struggle to clarify. According to my mum, Rose was not a very pleasant woman. Her Dad didn't like George Barrett either and called him Old Man Barrett!
