I don't have Albert's or Rosina's birth certificates yet.
Thank you for locating the information on Fanny Kezia Jay, that's another avenue to explore.
This birth entry would correspond with her dob of 3 July 1877 as shown on her baptism record
JullAug/Sep 1877 Chelsea 1a 319
Rosina WATTS
The only way to be certain if you have the correct Rosina Watts on the censuses with her parents Edward Albert/Albert Edward Watts occ Baker & Frances/Frances K ? would be to obtain her birth certificate to confirm her mother’s maiden name
If it is JAY then you have both Edward/Albert & Frances Keziah father’s names from the marriage details posted
It looks as if Edward Albert Watts & Fanny/Frances Keziah may have named some of their children
after their respective siblings/parents, if I have the correct families on the censuses
Edward Albert Watts & Frances Kezia their children's names from their baptism records
