I need to get below data only, when I provide "Vishal Group1" value in 'Description' column, as a condition in SQL.

In tree format, the logical structure looks like as below:
Vishal Group
|
|-------Vishal Group1
| |----------------Vishal Group1.1
| |--------------------------Vishal Group1.1.1
|
|-------Vishal Group2
| |----------------Vishal Group2.1
| |--------------------------Vishal Group2.1.1
|
|-------Vishal Group3
|
|-------Vishal Group4
| |----------------Vishal Group4.1
I tried self join but couldn't get above result when I specify the above mentioned condition.
Actually, the requirement is, I need to visit the lowest root for every group (groups which falls under 'Vishal Group1' because he is the base group.) if that group is not used in specific table then I would delete that record from respective table.
Please help.
Thanks In Advance.
With Best Regards.
