Ah Right I see, I found a map somewhere online today which I think showed the Ruthin Rd old burial ground so it wasn't too far from where they all lived.
I know the Ruabon road opened in 1876 and the Mulligans you list are all related. They are the graves I've visited. There are a couple of names mixed in there that I can't tie in but I'll have to contact cemetery office about them. I found another grave there (not Mulligan) that has 2 people listed in a grave that are not actually there. Even though I checked it about 8 years ago these people are still showing as being in there) I couldn't tie them in and when I went to the office they checked the original books for me so I wondered whether it might be like that with the names here I don't recognise. I've also noticed this afternoon in the online burial records I've checked for various siblings, children, etc some of them appear to have another burial listed which supposedly took place many years after the last person I was searching for. These I cannot relate either but that's a whole other story to research. I even wondered whether they had started re-using the grave numbers but in a different section ( i e 2 graves with the same number but in different sections of the cemetery)but it shows up online as being in one grave, I don't know it's just a thought I had.
