My advice: learn lighting so that you know what you need for the look you want to create. The reason Elinchrom has so many light modifiers is that each one gives you a different quality of light. We can't possibly know how you want to light family portraits. That said, the larger the relative light source in relationship to the subject, the softer the light. So if you are looking for soft light, you need the largest modifier you can get your hands on (which means more power from the strobe) and for large families, possibly more than one!
