Thanks for the comments everyone
@SwedishEdith That's interesting about Saint Claire/Sinclair- particularly as it's used as a boy's name!
@Neurodiverse @LT2 - had to Google impractical jokers as hadn't seen before! I think it's probably something I can live with. I guess this is a risk of using names that aren't common in the UK - if people have only ever heard it in one context, they'll forever associate it with that. So we'd have to hope no one called Santiago ever becomes famous here for a really horrible or embarrassing reason...
@iloveorange yeah, it's interesting how the same names come in and out of style in different countries. Also I think when it's a name that doesn't exist in your own language, you're just really focused on the actual sound it makes and you don't have any of the connotations around associating with a certain type of person, so it's hard to judge how it will be received. My DP has suggested British names that I would never use as can't imagine anyone under 50 with them and I've done the same with one or two Spanish names...opinion seems a bit split on Santiago though, with several people saying they know Santiagos of all ages, including children
I quite like some of your suggestions too - you understand what we are looking for- a Spanish name that English people won't completely mispronounce ( or an English name that would be read correctly in Spain). So all J names - Jaime, James, Jorge, Joseph etc are completely out!
@elenacampana no, I never met a Spanish Tiago either, but DP tells me it's starting to be used as a baby name in Spain, so apparently there are some young ones (sometimes spelled Thiago, I think) I've been told a few times now though that it's definitely not used as a nn for Santiago, which seems odd to me as they are historically from the same name I believe and 'Tiago' is right there in the name Santiago, but apparently it just doesn't work like that.
I did want a name with more that one nn option, but I really like the nn Santi, so that's probably what I'd use for him
anyway
DP likes Tiago and also Diego, but I told him I think a lot of people here will automatically think of Diego Maradona, who was considered a bit of a villain here as a lot of people have super long memories when in comes to football!
I just also really love that DP has the personal connection to Santiago de Compostela, so it feels like a name with meaning for us.
