Teri Lyn Wright is the daughter of Jean Anne Heuer Bogunovich Wright.

Teri Lyn was 26 years old when she died. According to California Death records, she died in San Francisco on 17 Feb 1980.

California, Death Index for Teri Lyn Wright lists the following:
Mother's Maiden Name: Heuer
Father's Surname: Bogunovich

Where the Bogunovich came from is unclear. I cannot find any official records (no marriage records, no cencus records, etc) other than Teri's death record that lists her mother's maiden name as Heuer and her father's surname as Bogunovich (and a 1957 marriage announcement that lists Teri's mother's name as "Jean Anne Bogunovich").

Teri's grave marker lists her last name as Wright, but the official Madronia cemetery records list her name as "Teri Lynn Wright (Bogunovich)".

Teri was never married, so "Wright" is not a married name. Instead, I think it is the last name of the man her mother married later. I located his name in two places: "BG Wright" and "Bobby Gene Wright". In a newspaper article (November 1957, in Santa Cruz, CA) as "Bobby Gene Wright" announcing the marriage of "Jean Anne Bogunovich" to "Bobby Gene Wright"), and in a newspaper article (November 1960) as "BG Wright", announcing the birth of their third child, Tonja Ann. Teri Lyn's name, as well as another sibling Tisha Marie, are mentioned in the article announcing the birth of the third child (Tonja Ann).

Teri's mother's maiden name is HEUER. Teri's mother's birth name was Jean Anne Heuer.

Jean Heuer's father and mother are Margaret and Eugene Heuer. This makes Margaret and Eugene Heuer the maternal grandparents of Teri Lyn. Both of the Heuers are buried at Madronia along with Teri.

Margaret is buried at 72 E No. 14.
Eugene is buried at 72 E No. 15.
Teri Lyn is buried at 72 E No. 15.

Teri is buried in the same grave plot (72 E No. 15) as her maternal grandfather Eugene Heuer (father of Jean Anne Heuer). However, within a short distance of the Heuer burials are two Bogunovich family members who are the same age as Teri's grandfather. They are both buried at location 73 B No. 3. I assume these two individuals are the parents of Teri's biological father (Bogunovich). That would make those Bogunovichs Teri's paternal grandparents. I cannot find proof that the Bogunovich's ever had a son though. The only proof of children that I could find was the naturaization record for George Bogunovich where it lists their daughter Madeline.

There are no other Bogunovichs buried at Madronia.

My assumption is that Teri's mother (Jean Heuer) was first married to a Bogunovich (first name unknown) and they had a baby, and they named the baby Teri Lyn Bogunovich. My assumption is that the Bogunovich father is the son of the two Bogunovich's who are buried nearby (the ones who are the same age as Teri's maternal grandfather Heuer.) So, I assume that those two Bogunovich's are Teri's paternal grandparents.

Then, in 1957, when Teri was about three and a half years old, her mother Jean married "B G. Wright" and that is how Teri got the last name Wright. I assume that Bobby Gene Wright is Teri Lyn's stepfather.
