We have a thread dedicated to writing sentences and getting feedback 
I think that’s grammatically correct, but usually one would say something like this:
パトリックさんは55歳です。 Patrick is 55 years old.
Usually that would be:
お母さんはパイロットです。 My mother is a pilot.
or for the non-kana word instead of パイロット - 操縦士:
お母さんは操縦士です。
Also, assuming one is talking about one’s own mother (which is the case when no extra context is given), 母 is sufficient:
母はパイロットです。
I would say イギリス人, since it’s nationality. イギリス alone refers to the country.
If you want to emphasize that Edward comes from England:
エドワードはイギリス出身です。
