Margaret Yapp had 3 children before she married my great grandfather.
Mary c.1894
Annie c.1895
Alfred William 04 Aug 1897
Alfred William is the only one I have a birth cert for, there is no fathers name given. After their marriage they had a further 2 children Albert George and Thomas ( Albert was my grandfather)
On the 1911 census only Albert and Thomas are named as son's. Ann and William are Step children (Mary isn't at home)
So the story goes, Annie got her self in the family way and was put into an institution in Bishops Castle, where she remained for most, if not all of her life. Not sure when this was, I did ask at the archives but they said the records were closed for 100 years.
I have found an Annie Pressdee as an inmate in Bishops Castle, Shropshire in 1939. The only problem is The one in the image above was born 24th October 1895, the one in the institution (transcribed as 'Pressdie'

) says she was born 11th January 1896, she is single.
Ps. all the step children born Yapp took the name Pressdee later.
