Hi Jim
Now I am a little confused.
First of all my apologies, I should have been clearer - the Clementina Mary Ann Batt I meant was my great grandmother, born in 1887 to Thomas Benjamin Batt (not Benjamin as I said below). Thomas was born in 1854, but his parents I have as Thomas Batt, rather than his brother John, and Charlotte Clementina Burwash, married on 19th Dec. 1853 in Islington (ref 1b, 394).
According to the London Births & Baptisms records, Benjamin and Catherine had 3 children all christened on the same day, April 27th 1834, in Shoreditch: Eliza, born 10th Oct 1828, Thomas born 4th March 1830, and John born 6th April 1834. The address was New Inn Yard as you say.
I had wondered whether there was a connection with the famous musical Batt family of Kent in the early 1900s, because of the music hall link I mentioned before, and my great grandmother (born in Folkestone) apparently saying her family were on the stage - although nobody believed her! But I have yet to prove the link.
Regards
Jan
