Hi
I was in Bray this afternoon and took a stroll up Chapel Lane. Yes, there is an old pub on the corner, but also, if your ancestor worked with horses, he may have been employed in nearby Kilruddery Estate, home of the Brabazons (Lord Meath). This estate is at the southern end of Bray, not far from where your ancestors lived.
If you'd like to pm me, there might be good news for you.
Cheers
