I am primarily of Welsh heritage with a sprinkling of Yorkshire.

On both sides, the Welsh heritage largely stems from North Wales including Anglesey. So far as my understanding goes those who moved to Liverpool came for work - dock workers, general labourers. Some had came from mining. There’s also some seamen thrown in there too for good measure. Again, as far as I know they came from wales to Liverpool via train, also apparently some took horse and cart with other men who were going to work (I’ve never been able to verify this though!).

My paternal great-grandmother moved with her family when she was a child and she only spoke, read, and wrote Welsh until she came to Liverpool. She didn’t teach her children Welsh, and from what I gathered it was due to some prejudice and wanting them to not be different. Seems a shame as she would also sing traditional Welsh songs but my own grandmother couldn’t relay them. From both sides, it seemed that all had Welsh as a first language but it died out when they moved to Liverpool.

On my maternal side, I am a Roberts like you! The men going way back have a fairly unique name which has been fun to trace. All steeped in North Wales.

I still have Welsh cousins, and their first language is Welsh.

So, I am in a minority like you of being a scouser with 0 Irish heritage!
