My DD is an Independent Celebrant, who has conducted several services during the Lock Down. All have been very brief with only a handful of mourners (One had only the widow in attendance) but she has taken the full story from the relatives, written up the longer eulogy and sent it to them on line so that they can share it with others unable to attend.
Most of the bereaved families have requested that she does a memorial service, at some time in the future, when all friends and relatives will be free to attend.
