You're looking for a long standing MP who's sheltering a local resident at:
N 52 (H)(B).(F)(D)(E) W 001 (A)(B).(A)(G)(C)
It's unlikely they were mentioned at the first public meeting about the canal in (ABCD). Parliament would have already been aware of them before the canal was promoted during (ABCE). They would have stood by the time the canal opened in (ABCF). If you walked the entire length of the canal to find them you would cover (AG.BH) miles.
Please handle the container with care and keep an eye out for biking muggles.
