I don't think people read "Asexual and Aromantic" as "Asexual AND Aromantic" (At least I wouldn't). But I think "Liverpool and Wirral Asexual and Aromantic Social" is too long as a name and the two "ands" sound strange. I personally would only include the city you meet in in the name. If I searched an aromantics group in my area I would try all the major citys in my area. It would also help if you just include one post on the website etc. where all the names of cities around are listed so it shows up with the search results. But this might not even be becessary, as google is quite good with showing search results from other cities even if they don't match the search query exactly. I think I would go with " Liverpool (area) Asexual and Aromantic Social", but I don't have any experience with any of this. This is just personal preference.
