Default Trying to combine multiple records into one record in a Query

I originally cross-posted this question in microsoft.public.access.queries &
microsoft.public.access.tablesdbdesign newsgroups, but did not get a
response.

I am new to Access, and very little knowledge about SQL. I read allot about
normalization, need to know if I went to far with it with my Family table.
Here is the structures for the tables I have, and of the query I want to
create.

Contact Table:
tabContactID (Autonumber)
ContactID (Create using VBA in a form) (PK)
FirstName
LastName
etc....

Example:
tabContactID ContactID FirstName LastName etc....
0001 DonDuck Donald Duck
0002 MicMouse Mickey Mouse


Next the Family Table:
tabFamID (Autonumber)(PK)
ContactID (FK from Contact Table)
FirstName
LastName
FamRelshp
Birthdate

Example:

tabFamID ContactID FirstName LastName FamRelshp Birthdate
0001 DonDuck Daisey Duck Spouse
0002 DonDuck Huey Duck Chld1
0003 DonDuck Dewey Duck Chld2
0004 DonDuck Lewey Duck Chld3
0005 MickMouse Minnie Mouse Spouse

I would like to be able to create a Query, creating a single record for each
family, using the multiple records from the Family Table, based on the same
field, ContactID.

A Query with each record as follows:
ContactID
SpouseFN
SpouseLN
SpouseBirth
Chld1FN
Chld1LN
Chld1Birth
etc...

Or should I just set up the Family table like the above query.

Based on your data, I would create a table tblFields4Xtab with a single text
field [FieldName] and three records with values FName, LName, DOB.

Then create a crosstab with this SQL:

TRANSFORM
First(IIf([FieldName]="FName",[Family].[FirstName],IIf([FieldName]="LName",[Family].[LastName],[Family].[BirthDate])))
AS Expr1
SELECT Family.ContactID
FROM tblFields4Xtab, Family INNER JOIN Contact ON Family.ContactID =
Contact.ContactID
GROUP BY Family.ContactID
PIVOT [FamRelshp] & [FieldName];
