The name to search for in the index is Thomas Buddes.
Note you need to make sure you make a notation of the volume, page and memorial deed number.
I also note the familysearch film number and page AND copy the URL into my personal family history software.
Marriage settlements can be hard to find, for example, I have a marriage between Charles Creed and Catherine Norris but the name on the index is Knight, a close family friend and barrister.
Sorry I just realised you meant the earlier deed.
