Muriel Holland

Not related, as far as I know but definitely a contributor to Robin Annual.

According to a blurb in one of her books, "Muriel Holland was one of a family of six children. She was born in Wales but went to school in Bristol and now [1959] lives near the Zoo in London. She often visits it to draw the animals. She writes stories and rhymes for children and has had her stories broadcast all over the world."

Born in Cardiff, she was educated at Badminton School, Bristol, and contributed widely to the press and magazines, including The Times, Daily Telegraph, The Guardian, Evening News, Sun, Church Times, News Chronicle, Weekly Scotsman, Western Mail, Christian Science Monitor, In Britain, What's On In London, English Song and Dance, various women's magazines, the BBC -- both radio and TV -- and radio stations around the world. She also wrote folk songs (with music provided by Jim Parker), her lyrics published in Sounds Like Folk and Folksong Today.

She lived at 10 Elsworthy Terrace, London N.W.3 in the 1950s and early 1960s, moving in around 1964 to a flat in Goldhurst Terrace, Maida Vale, where she was still living in the late 1970s.
