Requesting a Cone-where to start?!

Hi All,

I am trying to obtain a CONE for my GGM for a possible court case in Rome and am feeling very overwhelmed. This is the last document I need and want to make sure it’s correct given the turnaround time and cost.

My GGM involuntary lost her citizenship when her husband (my GGF) naturalized in 1905. I have his naturalization documents and I have a certified letter from the county saying there is no record of naturalization for my GGM or any of her possible aliases.

I know I need to request a CONE but am unsure of where to start. Do I need to file a FOIA request? Request an index search? What type of CONE am I requesting? Do I also need anything from NARA?

I read the Wiki but am unsure what steps apply to me.

Any advice or suggestions are greatly appreciated! Thanks!
