@J.R.Ellam:
Thank you, sir. I place a lot of confidence in "dobfarm," and he appears to place a lot in you. So I value your input! I think we are "on the same page" regarding Owlet Hall.
I am at a disadvantage, being so far distant from these interesting places. The "Coldroyd" to which I refer is on the right as one goes uphill on Cold Royd Lane, and it is tucked in between the railroad grade and Newland Road. Fortunately, it is a Grade II listed building.
Coldroyd seems to have lent its name to a hamlet after construction of the house(s) partway up the hill on the left, visible in the postcard view. It is these (since demolished ??) which I suspect of being Owlet Hall. (Compare "Lascelles Hall" the residence giving its name to Lascelles Hall the hamlet.)
By "navigable" I meant worthy of a motorcar's use. From photos which relatives have taken of Cold Royd Lane and sent to me, I should be very reluctant to drive my car beyond Newland Road, although it is very inviting as a footpath.
Thanks also for the Bates cricket reference. My third cousin, the late Maurice E. Broadbent, was not only very interested in family history but was, I think, also president of the Kirkheaton Cricket Club at one time. He and Mr. Bates no doubt were acquainted if they were contemporaries.
And, finally, what is your opinion on any relationship between the present "Coule Royd" street in Dalton, Huddersfield, and our good old "Cold Royd Lane"? I ask because of the XVI.- and XVII.-century references to the Norths, which sometimes list them as "of Coldroyd" (which fairly assures one that it is our family) and sometimes as "of Couleroyd" (which, until recently discovering the existence of Coule Royd street, I thought was a variant of "Coldroyd").
Thanks for your reply.
