I am a volunteer for Ireland Reaching Out and I look after messages relating to Co. Antrim.
You posted about Hector recently. Could you add any more details? The information at the moment is rather slim.
I think if you were to add a bit more you might increase your chances of matching with others researching that family. Religious denomination, occupation, parents names, siblings, approximate date the person left Ireland and so on can all help. And obviously if you can narrow the area where they lived in Co Antrim that’s helpful too.
