There is a marriage in the June 1/4 1960 in Ilford, same place as Ronald was married, For a William K. The marriage is recorded as both Williams and Phillips-Williams, the same as Ronald. My inkling from that is this is likely to be Ronald's brother and the K is for Kenneth, William having been added to his name.
Ah thank you. That's the same conclusion I reached but wanted to check if you had any other info. Thanks for the clarification
