Your husband's tastes in names are certainly wide-ranging. JenniferAnn for a girl is acceptable, but very white-bread and somewhat too common (the number of Jennifers already on the planet - including my dear spouse - rivals the population of India).
Isreal Ikaika? This name screams "NYPD police brutality". It sounds like a hapless Senegalese immigrant who might meet an untimely end at the hands of the Boys in Blue. Possibly administered with a Salad Shooter...
As for your own choices, please avoid "Trinity". It brings to mind a second-rate gunslinger in a cheap Western paperback.
That said, I have confidence that you two ultimately will find an acceptable compromise without domestic bloodshed.
