I dont think the ape titan is Erwin's father.

Just remember the last time of Mike facing ape titan. what's point here?The beast titan have no ideas about 3DMG!!! 3DMG was invented in year 775, about 70 years before beginning of main story. It is not so "unpopular" that Mr.Smith is suprised of 3DMG apperiance when exterminate Mike.

Just think about that!
