Rabbi, Thanks for the answer, but you didn't say whether an Englishman can keep 3 hours? shavua tov

ב"ה Halacha recognizes waiting 6 hours between meat and milk and the minhag of Dutch Jews who wait one hour and that of Jews from Germany who wait 3 hours. To the best of my knowledge in regard to waiting between milk and meat, Halacha does not recognize an "English" minhag in this context, although there are many minhagim kept in England which stem from German Jewry. Therefore, in regard to your question, if you know that your family has the minhag to wait only 3 hours as the minhag of German Jewry, then you can continue doing so and it would apply also to meat not just poultry. If on the other hand, you are not aware of such a minhag in your family, you should keep the custom of waiting 6 hours between meat or poultry and milk as written in the Shulchan Aruch and recommended by the Rema (שולחן ערוך יור"ד סי' פט) and as accepted upon most of the Jewish communities.
