We have numerous times throughout  the year that I need to create a list of students sorted by family (familyID) and oldest to youngest.  1) for applying graduated multi child tuition discount 2) sending home printed materials or family directories 3) producing demographics on # of families per campus not # of students....... Currently I use an unused field on Bio 2 in EE that I enter a "FamilyID"   ex: 89657-1 would be family 89657 and the -1 is the oldest child, -2 second child and the last child is denoted with a -9x.  Then I can create queries and lists of all those students in grades 1-4 that are the 3rd child in a family.  So I how do I gather families in like groups?  I need to know how to associate relationships between siblings so that legacy can be established.
