Sibling name for Isaac

[2silverheartsin1]

Isaac and Noah
Isaac and Luca
Isaac and Jacob
Isaac and Miles/Myles

I love both Noah and Jacob. They both match Isaac so well too, being biblical.

Luca is ok, but I prefer Lucas. Myles is my least favourite (but I much prefer this spelling, as it's not a measure of distance).

Noah - overused
Luca - too trendy, prefer Luke
Jacob - great
Miles/Myles - I don't like the Myles spelling

All are nice, Jacob is my favourite and Noah is lovely too.

Of your 4 options, Luca but I think I would go with Lucas. Noah and Jacob feel too biblical with Isaac. To my ears, Luca and Miles jar a bit next to the extremely classic Isaac.

I have an isaac and am currently pregnant, it's a girl but if it's a boy it was going to be Noah!

All of my DC were nearly called Noah (and I have an Isaac).

Ezra
Jacob
Gabriel

Noah and Jacob very biblical, would assume ye were very religious. I like Luca or Miles

also Lucas or Max

I like Isaac!

I like Benjamin with Isaac - softly biblical so it works with it, but without sounding like you opened the bible and picked names from it.

I like Luca, even though many say it's too trendy and also quite liked the suggestion of Gabriel.

I voted for Noah, but also like Jacob! I haven’t met a baby with either name…

Edited to add: I also like Gabriel

Hayes

Isaac and Jacob for me. Straightforward matching styles as they are both popular Biblical classics/semi-classics.

Noah and Luca feel trendy in comparison imo and Miles is a slightly different style to the others to me (would have used to been known as a bit “posh” before it became more popular).

I love Myles

Jacob is Isaac’s son as well.

I don’t see an issue with two biblical names but if that’s an issue keep it in mind. I don’t think it signifies anything unless you go for more obscure names.

I love all your name choices! You can't go wrong with any of those. Noah is a favourite of mine though.

I have a Samuel Isaac which obviously i love, but I also love Jacob
