Thanks, Alan.  I didn't realize one can zoom in to see that.

The Browns gave that name to the house because they'd been married on St Luke's day, 18 October.  I doubt the present occupants know that, and am a bit surprised the name has remained for all these years.

Never mind whether it has a number, Alan: thanks to you and that map we now have the grid coordinates.

My relative Richard Cecil Brown, a retired army captain, was living in a house overlooking Marlborough common from at least late 1947.  There appear to be no houses on Free's Avenue or Pott Hill, so I think the most likely place to look is the short street named The Common.

Does anyone have access to a street directory and would be prepared to search for him?

By 1955, perhaps earlier, he was at 'Four Winds' on Granham Hill, which I'm almost certain was on the site of the present Merlin's View.  It's the earlier house I'm trying to find the address of.
Oh, and in the 1939 Register he's somewhere quite different, so that won't help.

I did a test with Ancestry a couple of years ago and uploaded the results to MyHeritage.
The few matches that repeated Ancestry matches had considerably higher cM values.
Then there were hundreds of unknown people.  Many of the names looked Jewish. 
I know MyHeritage is an Israeli company, but I do not believe I have any Jewish ancestry.

Conclusion: forget MyHeritage!

When the 1921 census was taken, my grandfather (Richard) Cecil Brown was living at 'The Cottage', Great Comberton.  I'm sure there were many cottages in that village!  Does anyone have any idea how I might identify the right one, with its present-day address?

He had been invalided out of the Indian Civil Service after losing a leg in the Great War.
But I doubt anyone alive today will remember him or his family.
