it upset beatty greatly that his blindness meant that he could no longer see his racehorses. for a number of years, he needed to have someone describe the races to him when he went to a racetrack. his estate was valued at more than £306,000 in 1950, equivalent to £29.1 million as of 2013. mereworth castle was left to michael lambert tree, beatty's nephew. tree was a son of ronald tree, beatty's half sibling from his mother's first marriage. ronald tree's other son, jeremy tree, inherited beatty's bloodstock and became a racehorse trainer himself.
