Extra information:

Henry Duncan McLaren, 2nd Baron Aberconway CBE (16 April 1879 - 23 May 1953)
was a British politician, horticulturalist and industrialist.
Around the end of his political career, in 1920, he inherited the family estate
(originally his maternal grandfather's) in Bodnant, where he extensively developed
and added to the Bodnant Garden. He took interest in the breeding of rhododendrons and magnolias.
He sponsored several botanical collectors, including George Forrest, and Rhododendron aberconwayi is named in his honor. Most wellknown cultivars/clones are "His Lordship" and "Westhaven".
