Massa was a silverback who was born in the wild in 1971.
He arrived in Zoo Krefeld on 29 April 1975.
There he died on 1 Jan 2020.
A short (maybe unnecessary) explanation:
red = girl
blue = boy
bold name by parents (started at grandkids) = offspring Massa/Boma

** N'Gayla is her mom. According to the official studbook Gorgo (N'Gayla's dad!!) is also N'Yaounda's dad (incest). Omdat diverse kinderen zowel door Bauwi als door Gorgo verwekt hadden kunnen zijn, zijn er bij een aantal gorillas DNA-tests gedaan. Het resultaat was dat voor alle kinderen waar vraagtekens over het vaderschap waren, Gorgo de vader was. Sommige mensen trekken die conclusie trouwens in twijfel, helemaal waar het N'Yaounda betreft. Ik heb haar nu alleen als achterkleinkind vermeld, maar ze is dus feitelijk ook een kleinkind.
*** The girl who is a child of her grandfather according to the offical studbook, has a second kid of which the father isn't known yet (says that same official studbook). It could be Golo or her own son, Bongo, who was fertile and apperently mated with his mother. He is out of the group since a while by the way. He moved to Opole.
All data are taken by me from the official 2020 studbook, updated with news I found on Facebook and other social media.
Left out of this list are stillborns and kids who didn't make it till their first birthday (unfortunately there are a few; that's life).
Summary (situation up to date):
» 8 children, 5 daughters and 3 sons (2 daughters and 1 son died)
» 41 grandchildren, 20 girls and 21 boys (3 grandsons and 4 granddaughters died)
(N'Yaounda is probably also a granddaughter)
» 45 great-grandchildren, 20 girls and 25 boys (2 great-grandsons died)
» 6 great-greatgrandchildren, 3 girls and 3 boys

More about Massa and his females.
Like mentioned above, he arrived on 29 april 1975. A few months later his two females Tumba and Boma arrived (on 3 July 1975). In 1994 Oya arrived and in 1997 Muna. He never had kids with those females. Oya and Muna moved to another silverback in Zoo Krefeld in 2012.
Tumba has been pregnant 9 times, but it went wrong 6 times. That was all way before I was really into gorillas.The data I know from the official studbook; on the unofficial studbook I read about the causes of death. I don't know where they have that information from.
2 babies were aborted (??) and 1 was a stillbirth. One isn't mentioned in the unofficial studbook. Not as Tumba's baby that is, but as Boma's (and that is wrong I think, I believe what the official studbook says). The cause of death for that baby is stated: unknown on the unofficial studbook.
2 babies lived a few days (one 5 days, died of skull injury and one 6 days, died of malnutrition).
One daughter, Mueli, lived 16.5 months and died of proliferative bronchiolitis.
Then there were 2 more daughters. One is still alive and one died not long after she turned 24. You can see them (and their offspring) in the table above.
Poor Tumba with all her bad luck 
Boma had more luck with her offspring. She had only 1 stillbirth (29 Apr 1984).
Tumba died of old age on 13 May 2019.
Boma and Massa had the most horrible death possible. They died in the fire on 1 Jan 2020
