The only bloodline with any detail had the Von Cartsteins in it. Others were mentioned, but didn't have much detail
No rules involving bloodlines eh.
e.g. strigoi vampire armies make ghouls as a common troop type.
While lahmians never ever have ghouls (outright not allowed). However they can have thanes (heroes from other armies) and 1 rare slot for an enemy troop type.
So I guess you have the correct edition. Since the older edition really emphasised how different bloodlines armies were (which was kinda fun).
I personally loved running lahmian armies and getting a chaos tzeench champion and getting khorne berserkers or just normal warriors with mark of tzeench.
Then cheesing it out with spirit hosts, banshees (ethereal-immune to everything except except magic, so war machines, long range shots, melee attacks, all useless) and skeletons (just to fill in the points requirement).
