As such, your investment will only be risked up to your capital contribution.You normally will not increase your risk unless you guarantee a note or increase your responsibilities to that of a managing member or general partner.Creating an extra LLC may provide some 'anonymity" 

Some say that the benefits of this is that it gives you an extra layer of protection, anonymity (if you have the holding LLC in a state like Delaware) and additional ease in transferring money between the LLCs.

Land Trusts are a great tool for anonymity.

We form anonymous series LLC's in Texas then register that LLC all over the country but we don't use a WY LLC or other anonymous state. 

One provides asset protection and the other provides only some anonymity. 

Further, would an attorney be able to drudge my name up or would it be anonymous to him/her as well? 

They feel more anonymous and have deniability.   

However, I'm curious to know how you set up the entity structure of your business while maintaining complete anonymity.

Hi everyone, I have opened a second LLC (child LLC) in Florida, owned by anonymous parent LLC in Wyoming (which is owned by me).

You report everything to the board and the board sends anonymous notices.
