Moore / Bradley

Greetings all, I’ve had some success with my road block. I’ve attached a record for my GG grandparents - William Moore and Ellen Bradley (Eleanor). I have death certificates. To go to the next step - is there anyway of finding ancestors via their profession? William - I have all of his details. His father, Thomas Moore is listed as a staymaker (women’s undergarments?) and Ellen’s father was James Bradley, a bookkeeper (accountant?). I’ve contacted the Townsend church in Belfast - they have confirmed the marriage, but didn’t respond with any other details on these families. Ellen’s death certificate says she was born in Carrickfergus. I did contact one society asking for information, not successful. Also, I discovered that Margaret Bradley married a George Graham, also a Brushmaker (William Moore & George Graham were witnesses at each other’s weddings. The Bradley girls mother is listed as Jane Neill (married James Bradley).  Nothing on the mother for William. Is it a dead end for me or would it be a possibility info may be held in church records? A trip to Ireland to plan.  Thank you, Penny
