It is said on Wikipedia, that the precursor of blastocyst is a morula, and that the precursor of morula is a zygote. This gives us the part of genealogy tree of cell types. Unfortunately, no full genealogy can be found in Wikipedia.

Where can I find a more complete picture, preferably a full tree of cell types including information about each type?

Wikipedia has a page listing cell types which classifies their origin as endodermal or ectodermal.

I haven't been able to find a source for a complete lineage of all cell types, and I have gained the impression that there is no complete picture, except in some specific cases such as the haemopoietic lineage.

Here is a TEDX talk by a researcher in the field, and here is a slideshow by the same person which lays out the problem and its importance.
