Hello! 
I don't suppose anyone might know if there are any records of memorial inscriptions at Limehouse St anns. I've looked for them (or referrence to them) on: 
metropolitan archieves website 
east london family history website
find a grave 
deseased online 
billion graves 
the church (st anns)  website 
and on the guide to burials in london topic on this website. 
I am looking for Alexander lighterness who was buried in 1829 - I think he may have had a gravestone. 
thanks, 
Kate
