Good evening all!

Wondering if anyone can help! I am trying to locate the estate that my ancestors worked for during the late 19th to early 20th century. My Nain (grandmother) Lilian Nora Williams, was born in No1 Bron Rhedyn in 1909 - located on the A470 Betws-Y-Coed stretch. As she was born illegitimate she was raised by her Grandparents Thomas and Catherine in this property, as opposed to with her mother (also called Catherine) whom re-married.
As Bron Rhedyn (also known as Ffrith Cottage/ Castle) is shown as the family home for a few decades in the Census', it is possible that this property belonged to an estate such as Maenan or Gwydir. All the family had job titles such as Farm Bailiff (Thomas), lead miners/ coach men (Thomas' sons), kitchen gardner (lodger) and domestic servants (Thomas' daughters).
The main reason I am trying to trace the owners of this land/ property/ area is to work out where Lilan's Mother - Catherine worked. On Lilian's birth certificate Catherine's occupation is written as '
former domestic servant', former crossed out, and soon after Lilians birth, Thomas' occupation is somewhat demoted. I would like to eliminate any possibility that Lilian's father was connected to a nearby estate, although I am aware from other branches of my family this is a difficult task.
Any information would be greatly appreciated, calling all expert - historical geographers

Many Thanks
