Hello there, I am researching the Lumsden family from the Blackrock area in Dublin. I had gotten as far as a John Lumsden and Catherine who had children there in the early 1840s. Catherine's birthdate seems to be about 1807 and I had assumed John's would be from a similar date.
Once I noticed a John Lumsden birth recorded in Monkstown I was confident these two must be connected. Monkstown is right next to Blackrock. I see from online this record is connected to another John Lumsden. I just wanted to check if you were confident this is your John Lumsden so I can strike this from my list. Does your John mention a Robert and Jane in his records elsewhere or does he mention Monkstown?
