One of our most common requests here at Search Quest America comes from siblings who find out late in life that they have a another sibling that was placed for adoption. Some people are shocked that they were not told about the adoption, but most are also excited at the possibility of finding their missing family member.
Many siblings have very little information to start with when they are looking for a sibling placed for adoption so it's imperative that you do preliminary work prior to posting information on the Internet.
When you are in search of a sibling placed for adoption, the first thing you 'must' do is discover his or her date of birth and place of birth (city and state). Very few states have public resources that professionals can access to find birth record information. However do you have a starting point in that you know your parent's name at the time of the birth.
If possible, ask your mother or father for the exact date of birth. Ask if they named the adoptee prior to placement. Adoptees may have their decree of adoption which in all probability lists their name at birth. In many states this may be the adoptee's only document with birth identity listed.
If your parents are deceased, turn to other family members for answers. Check in a family bible for a date of birth. If someone in your family is actively recording family genealogy, check with that relative to see if he or she has a record of your sibling's birth. If you are Catholic there is a good possibility that your sibling was baptised within three days of birth. It may be possible to discover that date of birth by retrieving the original baptismal record.
Sometimes your mother or father's old friends may remember the circumstances if they knew about the birth and adoption. If your mother is deceased but her 'best friend' from that era is still living, odds are your mother may have shared details of the pregnancy and birth with her best friend. Reach out and talk to her about this.
The one thing that 99% of adoptees know is their date, city and state of birth. In order to 'match' on any registry site, or even to start sending inquiries to adoption agencies or state agencies you are going to have to be sure of your siblings date of birth for the best chance at a potentially successful match.
If you are positive of the state of birth of your sibling, check with the post adoption entity in that state to see if they have a sibling registry which allows siblings to register. You will need to fill out a form, and may also need to get it notarized. Include as much information on the form as you can, including both birth parents maiden and surnames as well as their dates of birth and the adoption agency used.
Good Luck in your Quest!
