Perhaps not relevant to this group, depending on successfully identifying the individuals involved, but in The Telegraph last week was announced the engagement of Sir David Walker and Lady Harding-

The details given are very limited, however listed amongst the supporters of the Royal College of Music are "Lady Annie Harding & Sir David Walker" (presumably, as is often the case, erroneously indicating her to be the daughter of a peer). The most likely candidate I can find would appear to be (Patricia) Anne (née Skelley), widow (m. 1994; dau. Emily Rose b. 1996) of the businessman Sir Christopher George Francis Harding (1939-1999; his first wife, Susan Lilian Berry, was granddaughter of the first Viscount Kemsley, and cousin of the Barons Rothschild); company records give a "Lady Anne Harding" as b. Apr. 1951 (and a "Lady Patricia Anne Harding" with the same birth details), a director of the Merchant Taylors' and Christopher Boone's Almshouses Charity; the Merchant Taylors' website shows "Lady Anne Harding" as having joined the livery in 2009. There's a 1951 birth record for a Patricia A. Skelley (mother "Mackay"). There are a few options for "Sir David Walker". If anyone can shed any light on this it'd be appreciated.
