I have been tracing an ancestor of mine Catherine Cowin (nee Jones).
I have been getting complacent and foolishly forgot to put in sources I had found for her DOB and the place of birth when I found them online, and now I can't think where I got them from. I know that I didn't pluck them out of thin air but it certainly feels like I did.
I have put her date of birth down as 24th of December 1878 for some reason, even though the 1911 census record I have placed her year of birth to be 1882. I have also placed her place of birth in Carmarthenshire. I have also entered that she lived on St Oswald Street, but can't remember where I got that from.
Can anyone help me backtrack and find the sources of this information? I'm feeling very stuck now.
