In Anderson's case, they did, posthumously. She was no relation to the Romanovs, and the Tsar's entire family was found, exhumed, and DNA tested since then.
The Metafilter discussion on this story goes deep into the reluctance of UK residents to install window screens. It highlights how downright tropical America is in comparison. We have a lot of summer and a lot of insects. Brits, on the other hand, only open their windows a few days out of the year and find themselves invaded by neighborhood pets, foxes, and hedgehogs.
