Maddingly Obscure Sig on Floral Plate

HELP

I picked up this gorgeous plate but I cannot for the life of me read the signature. I'm not expecting anything special but I'm so curious




There looks to be a large S shape before the first word, I've edited it to make it more clear.




So far the first word is Diad_i, with possibly the S in front of it. Second line is S_ff_lu? Or maybe Sudp__? After the f/p it looks like a dash, two more letters, than another dash and dot. No idea

​

 

Based on the style of it, I'm guessing the second word might be Soufflenheim.

 

Oh goodness, in all the kurfuffl about the urn I forgot to reply! I did a quick search before leaving the house yesterday and you're spot on, but most of the signatures are stamped rather than scrawled like mine. Not sure if that points to a particular potter or if thats going to be as close as I get, but thank you for a new style to look out for! I love it
