Laura - I ran across a Christmas photo greeting card of your family, circa 1962, in a Denton, TX antique store. Your mother is holding you in her lap, Mike is sitting on the bench next to her. Dennis is standing and your Dad is squatting on the end. It appears to have been taken in front of the family home.
The card is not addressed to anyone and doesn't appear to be a publicity shot. You and your family may already have this photo in your family archives, but if not, I am happy to forward to you.
I "rescue" family photos from antique stores and attempt to place them back in family hands. It's my way of blessing and giving back to the genealogy community.
Please accept my heartfelt condolences on the loss of your Dad in 2007 and your Grandfather this year. You may reach me at firstname.lastname@example.org if you would like the photo back in the family fold.
