Oh I absolutely love [name_f]Trinity[/name_f] 
I do feel this name feels very Catholic and I’ve only seen this name used within [name_m]Irish[/name_m] Travelling families who tend to be Catholic. Still I think [name_f]Trinity[/name_f] can broaden outside of Catholic communities and I actually love her! [name_f]Trinity[/name_f] feels spiritual, earthy and bohemian a gorgeous name with the fun nickname [name_f]Trinnie[/name_f]. Middle name wise I would probably choose a name that feels grounded and classic like [name_f]Elizabeth[/name_f], [name_f]Charlotte[/name_f], [name_f]Catherine[/name_f], [name_f]Florence[/name_f], [name_f]Abigail[/name_f] or [name_f]Margaux[/name_f]. I would name her siblings [name_m]Rowan[/name_m], [name_m]Shepherd[/name_m] and [name_m]Abel[/name_m] for brothers or [name_f]Evangeline[/name_f] (maybe too religious but love), [name_f]Marigold[/name_f] and [name_f]Paloma[/name_f] for sisters.
