References to the English aid lists for Huguenots post 1685 indicate two persons with the surname BEAUCHAMP, but there is little information on their descendants. It seems unlikely that this Louis or Pierre would be relevant to your research. Given the numerous examples of this surname, it is obvious that there must be other sources and from what I’ve seen, these may include Norman possibilities.

Breaking a brick wall requires a re-examination of the data at a greater level of detail. What documents and what sources have you used to substantiate the research you have done so far? Who are these other Beauchamps you refer to in the registers? Do you have other listings for 1800-1820? Do they fit into families and what is their history? Is there family history to be found in the documentation? Kilmersdon appears to have good documentary sources, if that is the correct location. And if it is not, then unfortunately one is often hard pressed to find indications of the actual place of residence.

The presence of the surname BEACHIM in the few extracted listings for Kilmersdon brings up the topic of spelling variations. What have you found in this area? Sound is often a more reliable indicator. Sometimes spelling is all over the place.
