[name_m]Hi[/name_m] there!
Iām sorry youāre having trouble picking a name for your third, but I hope I can help a little.
[name_m]Henry[/name_m] and [name_f]Annabel[/name_f] are both quite traditional, classic names. Theyāre youthful, yet stand the test of time, as do many of the others you have mentioned in your list.
You also mentioned that you like [name_m]Felix[/name_m], but worry itās too out there for where you live. For the record, I love [name_m]Felix[/name_m]. Itās fun and playful, but also carries some serious weight with numerous connections to great literature. You also couldnāt ask for a better name meaning; [name_m]Felix[/name_m] means āhappyā and āfortunateā. As for not fitting in where you live, the decision is ultimately up to you. If you really think [name_m]Felix[/name_m] is going to stand out too much, another name is probably best, but relatively speaking, I think youāre pretty safe. Itās also worth remembering that as people grow, they move around and change, so whilst [name_m]Felix[/name_m] might seem a little out of place now, thereās nothing to say he wonāt wear this name perfectly anywhere and everywhere in a few years.
Onto your list.
As mentioned before, [name_m]William[/name_m], [name_m]John[/name_m] and [name_m]Oliver[/name_m] all fit the mould of well-known classics. Theyāre unlikely to cause a stir, and particularly with [name_m]William[/name_m] and [name_m]John[/name_m], you have the benefit of honoring family members. That said, thereās nothing worse than being one of five [name_m]Williams[/name_m] in your class ā it takes the individuality out of a name.
Correct me if Iāve misinterpreted, but your idea to use a middle name as your sonās given name is one Iām particularly fond of. [name_m]Turner[/name_m] is a great name, and of course, you have the reference to artist [name_m]William[/name_m] [name_m]Turner[/name_m] with this pairing.
Whilst [name_m]John[/name_m] is well-known, I donāt feel that it fits with [name_m]Henry[/name_m] and [name_f]Annabel[/name_f]. It sounds a little old compared to these two, and consequently I donāt feel like youād be getting the best pairing possible.
[name_u]Everett[/name_u] is nice, although I think it works best as a middle name. [name_m]Oliver[/name_m] is also nice, and fits very smoothly with [name_m]Henry[/name_m] and [name_f]Annabel[/name_f], but is also a name well at the top of popularity lists, so not ideal if repetition was something you wanted to avoid.
I donāt know where youāre from, but [name_f]Annabel[/name_f] and [name_m]Henry[/name_m] are very quintessentially British. They fit into the refined elegance category of naming perfectly ā to match, here are some other names along the same lines:
[name_m]Arthur[/name_m]
[name_m]George[/name_m]
[name_m]Philip[/name_m]
[name_m]Louis[/name_m]
[name_m]Edward[/name_m]
[name_u]James[/name_u]
[name_m]Robert[/name_m]
[name_m]Theodore[/name_m]
[name_m]Hugo[/name_m]
[name_m]Peter[/name_m]
[name_m]Jack[/name_m]
[name_m]Richard[/name_m]
[name_m]Leo[/name_m]
[name_m]Julian[/name_m]
[name_m]Oscar[/name_m]
Favourites:
[name_m]Hugo[/name_m]
[name_u]James[/name_u]
[name_m]Arthur[/name_m]
[name_m]Oscar[/name_m]
There are a whole host of combinations you could try - [name_m]Felix[/name_m] [name_u]James[/name_u], [name_m]William[/name_m] [name_u]Everett[/name_u], [name_u]James[/name_u] [name_m]Turner[/name_m], [name_m]Hugo[/name_m] Hutton - the possibilities are endless. The great thing about these names is that they all fit together relatively well.
The name I think go best with [name_f]Annabel[/name_f] and [name_m]Henry[/name_m] are:
[name_m]Henry[/name_m], [name_f]Annabel[/name_f] and [name_m]Oscar[/name_m]
[name_m]Henry[/name_m], [name_f]Annabel[/name_f] and [name_u]James[/name_u]
[name_m]Henry[/name_m], [name_f]Annabel[/name_f] and [name_m]Felix[/name_m]
[name_m]Henry[/name_m], [name_f]Annabel[/name_f] and [name_m]Oliver[/name_m]
[name_m]Henry[/name_m], [name_f]Annabel[/name_f] and [name_m]Arthur[/name_m]
[name_m]Henry[/name_m], [name_f]Annabel[/name_f] and [name_m]Hugo[/name_m]
I hope Iāve helped, and good luck.
