Wow, BroJo... Some of those names are very familiar to me. My (non-jw) grandparents retired to CapeCod in the mid-70's and we used to spend alot of time with them there. And, of course, like good little JW kids, we attended the local Hall whenever we were there.
Jim and Renata were in the circuit work when we met them. They served our congregation in the early/mid 70's and stayed at our house for 3 weeks - twice a year for two years. My understanding is that they left the circuit work because Renata's computer skills were wanted at Brooklyn. I think she may have been involved somehow with MEPS???
As far as I know, Jim and Renata are still in Brooklyn. (They remained friends with my JW mother.)
Haratunian and Fragosa sound VERY Familiar. But that was a very long time ago... ;-)
