Hi
My suggestion is to do what I have done. Either buy yourself, or download a free, genealogy program (I use the excellent Legacy) and input all your data into that. You build the family tree as you go along, and can print out very good reports, including the actual family tree itself. Crucially, every person you input, gets a unique reference number, and what I have done is to get a card index, along with the box to hold them in, and each person can have their own card, onto which you can write all the facts that is known about that person.
I also have a document folder, and a photograph album, but because these are cross referenced to the card index, with the unique number. they are very easy to find if I am working on particular person.
This system has worked very well for me for many years, but the key to it all is cross referencing. Hope this may give you one or two ideas.
