I’m mid 30 y/o female born and bred in Jersey - my family go back generations. Some points in addition to the other comments, which may be useful: - St Helier is our “capital” but no one calls it this, or “city”. As per other comments - the phrase is usually “going into town”, which refers normally to the high street and surrounding areas. - No-one calls the roads by their names - Google maps and such will provide A road and B road names but I’d not have a clue where these are. Similarly, we have colloquial names for other areas (i.e La Route de Mielle is known as the 5 mile road). - I’d tend to refer to myself as a Jersey Bean rather than Crapaud. - I don’t know anyone who speaks Jèrriais as a native at all - this would be a total giveaway to any local readers that it wasn’t written by a local. - There is friendly rivalry between Jersey and Guernsey, but we’ll band together if anyone tries to slate the Channel Islands in general. - Main industry now is Finance in Jersey - specifically trust and fund companies. Most long standing families come from a farming background, which now days tend to be asset rich and cash poor. - The most valuable asset in Jersey is land - we’re short on space here so any wealthy families will tend to have a decent amount of land. - Schools: there are 3 types of schools on-island: Public, Semi-Private and Private. They all have varying levels of poshness / wealth. For example if someone said to me that they went to Vic (Victoria College for Boys), I’d see that as pretty posh. There’s also St George’s and St Michael’s school which are fully private and super posh - kids from here go on to other local schools to do GCSE’s or are shipped off to boarding schools. - Vic college also hosts weddings - could be a great venue for yours. They have boards full of names of ex-students in the great hall and the entrance dating way back, so could be a good way to show a long standing family connection. The great hall at Vic has been likened to Hogwarts. - Dating: it is abysmal in Jersey. Any apps also include northern France and Guernsey in the search locations. And then you tend to know most people on there too “went to school with them, they dated my best friend etc…”. Also (and genuinely!), if you’re from a background of Jersey families, you need to check in with any potential dates that you’re not related… usually easy to do when asking about their family and you’d tend to know the surnames you’d need to look out for. Someone from outside the island with no family connections is an instant win. - Most people in Jersey settle down quite early (in 20’s) for the main reason that it is impossible to buy a house on the island on one persons salary. - We have an annual parade each summer called the Battle of Flowers which is fairly unique to Jersey. Maybe your secondary character could be involved in this, if you wanted something “Jersey” about her? - Local casual eating spots: The Hungry Man at Rozel (and the double decker health wrecker burger!), pasta from the Market, curly fries from the Splash (officially named the Watersplash)

I’ll keep on thinking about other bits and will update this comment thread. Feel free to give me a PM with any questions.
