Finally got a response from Frankfurt Zoo; they have five aye-ayes. Male Malala and female Kintana, their adult son Kimala, and USA-born siblings Tsara (older sister) and Vinny (younger brother)

What was the reason for their death? I haven't heard yet?
@Nikola Chavkosk : Lemur death investigation continues, experts say no indication of infectious disease
Most recent article I can find.

Presumably, avocado is the reason for acute death of four aye-ayes in DLC. More accurately, the reason is the toxin persin wich is toxic for mitochondria; myocardyocites most prone. Avocado withdrawn from the diet: Avocados Blamed For Sudden Deaths Of Four Aye-Ayes
A very unfortunate incident and one which Duke PC center staff will have deplored dearly. However, nutritionally it will benefit future aye aye husbandry globally.
Even prior to this been communicated, given that the 4 individual aye-aye died shortly one after another it seemed likely that only a catastrophic event or infectious disease would be responsible for their quick deaths. I am really glad they found out relatively soonish and that now all other captive aye aye may benefit from improved nutritional protocols and advice (thanks to the Duke PC post mortem findings).

Yes, Two , both at Frankfurt Zoo. The first was born in 2010 but died a few days after, the second was born in 2011 and was raised succesfully, the male"Kimala",still at Frankfurt.
Update following a report released by the DLC specifically looking at the aye-aye (included a very handy pedigree sheet!!). This showed that Kali has sired a son at Philadelphia with Tolkein (the baby has been named Damien), Tiergarten at Ueno is actually called Tia and Malcolm at London is actually called Peanut! So we're still assuming that Ivoloina Zoo has 2.3 and Tsimbazaza Zoo has 3.3, but for now this is the world population outside of Madagascar.
EUROPE
Frankfurt Zoo (Germany) = 3.2 (Malala Kimala Vinny, Kintana Tsara)
Bristol Zoo (England, UK) = 1.3 (Noah, Sabrina Tahiry Kambana)
Chester Zoo (England, UK) = 1.1 (Raz, Mamy)
London Zoo (England, UK) = 2.1 (Tany Peanut, Salem)
Durrell Wildlife Conservation Trust (Jersey, UK) = 4.3 (Alain Patrice Pan Matoky, Zanvie Vassago Ala)
NORTH AMERICA
Cincinnati Zoo (Ohio, USA) = 1.1 (Nify, Medea)
Cleveland Metroparks Zoo (Ohio, USA) = 0.1 (Caliban)
Denver Zoo (Colorado, USA) = 1.1 (Smeagol, Bellatrix)
Duke Lemur Center (North Carolina, USA) = 3.6 (Nosferatu Poe Grendel, Endora Ozma Ardrey Lucrezia Medusa Elphaba)
Henry Doorly Zoo (Nebraska, USA) = 1.1 (Warlock, Claudia)
Philadelphia Zoo (Pennsylvania, USA) = 3.1 (Tolkein Loki Damien, Kali)
San Diego Zoo (California, USA) = 1.2 (Nirina, Styx Fady)
ASIA
Ueno Zoo (Japan) = 5.4 (Mamyroa Hitchcock Dimy Faly Mafy, Soa Hoavy Hira Tia)
So this leaves a total of:
11.10 in Europe
10.13 in North America
5.4 in Asia
5.6 (assumedly) in Madagascar
So a world total of 31.33 = 64 aye-ayes in captivity worldwide!

One thing I missed out on; females Sabrina and Tsara are reported to have died at Bristol and Frankfurt respectively in 2016. This means that there are 1.2 at Bristol and 3.1 at Frankfurt, so 11.8 in Europe and a world total of 31.31
Have just spent an enjoyable half hour watching London's female aye-aye and her youngster, the most active I've seen them! I was wondering though, with aye-ayes, is the male kept separate from the female and young? Are they always kept separate, or just introduced for breeding?
Ah so they're finally onshow
good! Generally males and females are kept separate apart from during breeding, though this may vary. All of the three zoos that I have seen aye-ayes at (Bristol, Chester and London) keep their male and female/offspring separate. So Noah lives apart from his twin daughters at Bristol though these latter two live together, Raz lives apart from Mamy at Chester, and Tany lives apart from Salem and Peanut (Malcolm) at London.
Thanks Jake, nice to know a bit more about their husbandry
A female aye-aye named Agatha was born at Duke to Poe and Medusa on July 7.
Rare Aye-Aye Born at Duke Lemur Center
Rare Aye-Aye Born at Duke Lemur Center
this from the Madagascar Fauna and Flora Group (2015) says there were five confiscated individuals but two died, so three left: Member News
In February 2014, five illegally held aye-ayes were discovered by a team of researchers from the Aspinall Foundation, Association Mitsinjo. In collaboration with the government of Madagascar, represented by Mr. Eric Robsomanitrandrasana, MEF-DVRN, the aye-ayes were confiscated from the Malagasy villager who was holding them in small wire cages at his home. Virtually no information about the capture location, history and recent care of these animals was available. One individual died shortly after being brought to Parc Ivoloina on March 3 and a second died despite intensive veterinary care provided by Dr. Cathy Williams, Duke Lemur Center. The San Diego Zoo responded generously to the MFG’s request to fund an off-exhibit housing facility for the aye ayes which was completed in October.
All the same, glad that 3 are left at Parc Ivoloina.
I wonder if any others are held in captivity on Madagascar at the moment. I believe that Antananarivo - Tsimbazaza still has some. How many, not sure ..

that sex ratio is not a defensible assumption (and your figures would be wrong anyway).
You had a 2011 total of 3.4 in your post #22 which is fine, but you then added a plucked-out-of-the-air sex ratio of 2.2 for the four animals lintworm mentioned, giving you 5.6. Then I pointed out that there were only three surviving animals of the confiscation, not four, and somehow that made you drop two animals from your total?
However you don't know the sexes of the confiscated animals. At best - assuming all the 2011 animals are still present and alive - you should have a total of 3.4.3.
