Marriage record help (Latin)

[liviomoreno]

I am translating a marriage record from Latin and I wanted to run it by you (hopefully) since there are some pieces not fitting in (my Latin is very rusty at this point!). Below I am posting the transcript in Latin and my translation, I am also attaching the scan of the original record.

These are my doubts:

1) quid Regiam Capellam - I am not sure about the quid. Shouldn't that be quod? I cannot read a quod. I read quod

2) After the names of the witnesses, I am not sure if it reads Londinii (gen. = of/from London), or Londinio (abl. = in London) I read Londini

Thanks!
