I have used the everyhit website for years. It's a great resource.

I wish there was a similar website for US charts, but I've never found anything.
The actual question is:
When did My Love And Devotion peak at #29 on the UK Singles Chart?
Here is the specific information about its chart run:
MY LOVE AND DEVOTION (BY MATT MONRO) Parlophone (R4954)
Date Entered: 10.11.1962
Peak : 29
Chart Run: 49-39-34-29-47--> 5 Weeks
