Their two sons were Robin & Kim
Here's some info on Robin
The son of two of Britain's best-loved comedy actors, John Le Mesurier and the late Hattie Jacques, Robin Le Mesurier took up guitar while in school, and at the tender age of sixteen, turned professional.
His involvement with numerous groups and studio sessions led to an extraordinary spell with The Wombles, a group of oversized soft toys that started out as characters in a series of children's stories and resulted in a string of hit singles. Suffocating in fake fur, Robin reached the top ten three times before being ousted from the group for "unwomblish" activities. Robin joined the survivors of the group Strider, to form Limey, but this band was short-lived, resulting in Robin's next stint as guitar tuner for the Rod Stewart Group, touring Europe and Australia during late '76 and early '77.
After reuniting with a newly-formed Strider band, Robin left the group once more to join another Rod Stewart tour - this time playing with Air Supply when they opened for Stewart in America in 1977.
Robin returned to England briefly to record an album with his father, but was back in the U.S. in '78 as a member of Lion. He then joined the highly-touted L.A. Band, The Difference, which helped pave the way for his present relationship with Rod Stewart. Having contributed recently to projects with Randy Van Warmer and on Ron Wood's solo effort, 1-2-3-4, Robin's non-stop ambition has led to his own "tongue-in-cheek heavy metal" single and Arrested, an album of orchestrated Police songs, both featuring the Royal Philharmonic Orchestra. In addition, the latest Stewart album, Body Wishes, features tunes co-written by Robin with Rod Stewart, Jim Cregan and Kevin Savigar.
