Tracing the history of any CMA is certainly a formidable task!
Lots of good information on various IMA styles, including their history and lineage charts, can be found on Jarek Szymanski's excellent website: http://www.chinafrominside.com/ma/index.html.
From my understanding, most of the information on the site comes from interviews with various masters that Jarek conducted himself and translations of Chinese texts.
He may be able to point you in the right direction for other history sources as well. I imagine though, your search will be restricted to the limited number of translated sources, unless you are familiar with either mandarin or cantonese.
