Is it more preferable to bury a woman with her father or with her sisters if the burial is either here or there?

The general rule is that each deceased person should be buried in a separate grave, unless there is a necessity to bury more than one deceased person in a single grave. If there is a necessity to bury a woman with others, then it is preferable that she be buried with other women. If there is a necessity to bury her with a man, then it is preferred that the man be in front of her and she behind him, with a barrier of earth placed between them.
