To marry in May is very unlucky and to wear green is worse.
Married in May and kirked in green
Both bride and bridegroom won't long be seen
O' marriages in May
Bairns die in decay
This little extract is from a Year Book written in 1826 by Hone
On May the 20th 1736 the corpse of Samuel Baldwin was immersed in the sea off the Needles on the Hampshire coast. This was performed in consequence of an earnest wish of the deceased in order to disappoint his wife who had repeatedly assured him during their many arguments that if she survived him she would revenge her conjugal sufferings by dancing on his grave!
It doesn't say whether they were married in May.
