Looking for opinions on baby #4 names

[name_m]Hi[/name_m] all! I’m currently 17w with baby #4 and trying to come up with names to go with my other 3.

We currently have:
[name_m]Jackson[/name_m] [name_m]Todd[/name_m] (both names were my ex-h’s choice)
[name_m]Maximus[/name_m] ([name_u]Max[/name_u]) [name_m]William[/name_m]
[name_f]Izabel[/name_f] (sometimes [name_f]Izzie[/name_f]) [name_f]Nora[/name_f]

I’m 95% sure we have our girls name picked (but still open to opinions), [name_f]Amelia[/name_f] [name_f]Irene[/name_f]. I’ve also kicked around [name_f]Amelia[/name_f] [name_f]Grace[/name_f], but I don’t love it as much. Other girl names we kind of agree on:
[name_f]Vivienne[/name_f] [name_f]Grace[/name_f]
[name_f]Ella[/name_f] [name_f]Irene[/name_f]
[name_f]Juliana[/name_f] [name_f]Irene[/name_f]

Then there is [name_f]Charlotte[/name_f] [name_f]Irene[/name_f], my ultimate fave but DH says no way.

[name_f]Irene[/name_f] is my middle name and was chosen for me because a great-grandma on each side of my family was named [name_f]Irene[/name_f], so I’ve really always wanted to use it as a mn for a little girl. We initially were going to use it for [name_f]Izabel[/name_f], but decided to give her my mom’s name as her mn because my mom plays a very big role in our lives.

But we are totally lost on boy names. It doesn’t help that we really don’t agree easily on names. Honestly, it was only just today DH finally said he could do [name_f]Amelia[/name_f], which has been one of my front runners from when we found out I was pg.

I love [name_u]Finn[/name_u], DH doesn’t. He likes [name_m]Silas[/name_m], but I don’t like the way it sounds with the other kids. That’s about as far as we’ve gotten with boys. I’m far more picky with boys names than girls names.

Here are my only boy ideas (I’m definitely looking for more):
[name_m]Silas[/name_m]
[name_m]Zachariah[/name_m]
Sullivan (nn Sully) Blake (as of tonight this is our front runner)

So if we do our front runners our kids would be:
Jackson, Max, Izabel and Amelia OR
Jackson, Max, Izabel and Sullivan

Thoughts?
If it helps we have a very Polish last name, ends in -cki.
