Oh! So assuming your iID is in variable m.iID:

>This is an excellent start, but it stops just short of what I need.
>
>Query 1 returns the descendents of EVERY parent. I need it to return only the descendents of parent with a given iID.

SELECT * FROM tblFamily ;
    WHERE iParentID == m.iID

>Query 2 returns the parent of EVERY child. I need it to return just the ancestors of a child with a given iID.

SELECT tblChild.iID AS C_iID, ;
    tblChild.iParentID AS C_iParentID, ;
    tblChild.cInfoAndStuff AS C_cInfoAndStuff, ;
    tblParent.cInfoAndStuff AS P_cInfoAndStuff ;
    FROM tblFamily tblChild ;
        INNER JOIN tblFamily tblParent ;
            ON tblChild.iParentID == tblParent.iID ;
    <b>WHERE tblChild.iID == m.iID</b>

>Thanks again for your help.

Glad I can be of assistance!
