Leonard died in Paignton Hospital, Devon, presumably whilst on holiday. It's always sunny here until October. I am guessing that his body would have been returned to Cheltenham.
Yes, his wife Elsie Winifred died on Monday, 1st December 1980 at Cheltenham, age 86.
I don't expect to find him buried with his wife as they appeared to have separated.
It seems that by January 1936 Leonard was no longer living with his wife Elsie. The Gloucester Journal reports on Saturday 19th January 1935 Elsie had applied to the courts for maintenance. She won the claim and Leonard was ordered to make payment.
