What do you think? (baby boys name)

[EbaneezerScrooge]

We are expecting a little boy sometime in the next month and cant quite figure out the name.
We both like Jack and Sirius so thinking Jack Sirius?

Other names we like are;
David, Isaac and Charles.

We don't mind if there's 2 or 3 middle names but we would definitely like Jack to be one of the names (first or middle).

Any one have any opinions?
(Feel free to make any other suggestions)

PS. Its a 2 syllable surname :)

Like David, Issac Id quite nice. Sirius, don't like and Jack, too overused.
When you see him you'll know what name suits him

There are a lot of jacks around, which might bother you? Maybe Jacob?

[Nereida]

I love Jack but not Sirius.

[Wishfulmakeupping]

I like David. Jack is ok but bit popular for me. I really dislike Sirius and Isaac sorry just not to my taste but I'm very old school

[steppemum]

Isaac obviously

not biased at all no not me

by the way dontgotosleep it is Isaac not Issac (sorry, constantly correcting it...)

[ButterflyOfFreedom]

Love Isaac and Jack so would use a combination of these.

Love Isaac!! Wonderful name!! Jack is overused. Sirius ...hmmm....to my mind it is stupid...i do not think this name fits to a human...imo
