There are countless memoirs available, and from any desired period in history. Every human being has a 'memoir' hidden inside; a few dare to put them on paper. You might have the writing skills of a deity.
But if your memoir is like the countless memoirs that have come before, no publisher will touch it Your memoir should have a serious twist or hook that will appeal to readers. I know you are sure that yours does. But if you research titles, you will surely find thousands that have the same 'unique' twist that you thought was original.
Search, search and search some more. Find out what kind of 'twist' accompanies the successful memoires, and which ones turn out to be duds Find out what publishers are handling the kind of material you wish to write Make this part of the title search Write some material-- the whole book if you have it in you And then throw it away. Literally Re-write it, and possibly re-write another time or two.Re-work, re-organize, re-think Go to your publisher's list and send a proposal in outline form of the book as you envision it, and make sure your 'hook' is sparkling and appealing.
Send it to as many publishers as you can afford postage for. Don't be surprised or dejected if you get hundreds of rejections. And suck it up when the publisher that accepts the proposal asks you to re-write all the sections that you consider to be inspired by God himself.
