I found the info for the Sparks Quarterly!
To purchase copies of the Sparks Quarterly you need to contact Dr.
Russell bidlack, the Secretaty Treasurer of the SPARKS FAMILY ASSOCIATION
and Editor of the Quarterly.
Dr. Bidlack's address is: Russell Bidlack 1709 Cherokee Rd. Ann Arbor, MI 48104-4498
The ASSOCIATION sells back issues for $4.00 each to non members and for
$3.00 to members.
Memberships are $10.00 per year for a basic membership,
15.00 per year for a contributing membership and any amount over $15.00 for
a sustaining membership.
If you write Dr. Bidlack and give him information the Sparks line you are
interested in, he can probably suggest which issues have information on this
branch of the family.
The Quarterly has been published continouisly since March 1953. There are
four issues a year.
