I am so confused/uneasy and need advice

To make a super long story short…
My girls all have my middle name which is also my mom’s middle name
My boys have the same as their dad and his dad

Ok here is the problem…
My mother and I now no longer speak, learned through counseling she is just not mentally ok…at… all… so that has a HUGE effect on me emotionally. So I am in a place where life is just shocking and such… in the meantime I am a little closer with my biological dad. Turns out he is pretty level headed and a blessing.
One of my kids was named after my step grandpa (my stepdads dad) and so I guess I am so worried that my mental mom will of course find out that I planned to name my newest son after my real dad that it makes me extremely uneasy.
She is honestly some scary stuff so I feel like if I name him after my dad she will flip out even more but I also like my dad’s name anyway even if it wasn’t my dad’s name…
Sorry for all the confusion… should I use the dads name as a middle name instead?
The boys middle names are all [name_m]Alan[/name_m]… My dad’s first name is [name_u]Michael[/name_u].
I thought maybe [name_u]Micah[/name_u] but hubby thinks it sounds kinda off… it’s just not us.
My first name Ioved was [name_m]Knox[/name_m] and hubby hates it.
Oh and I also screwed up by mentioning to my dad the name thing… so I also would feel super guilt to now not use it… ugh! These hormones are not fun!

I would continue with the trend of using dad’s middle name. I wouldn’t switch it up this late in the game.

I agree with this.

I agree with this too.

I think it’s fine to name a child after your biological father
