Not good to open Facebook Business page without personal?

I read a few websites that recommend not to open just a Facebook business page without having a personal page as well. They mentioned that in your personal page, just add a business page to it.

Here is my issue. I am starting a new project that is targeting a specific industry. So far I have created brand new accounts for:

gmail email account
google plus personal
google plus brand
youtube
pinterest

All these accounts have been created for the specific industry with no relation to my personal youtube or gmail accounts.

I already have a facebook personal account but not sure I want this tied to my friends & family. I will be using my real name for this project so I am not worried about hiding my identity but don't know if I want my personal account to be tied to this new one.

Do you recommend making a 2nd personal account and then adding the facebook business/brand page to that one?



Another questions:

There are many people that make money off of topics, say pug dogs or german shepherds. For those that do this, do you just create an alias and brand new facebook account, youtube account, google plus account, etc....?

Thanks
