I have this table where 3 columns could have same information where the last 4 columns can sometime be the same and other times can have different values.

In below sample that you will also have in the attachment, you see that Brampton John Carson have 3 records but when you look at the columns Result1 to Result4, 2 rows are the same versus the other is different.

As for Ajax Bruce Saxton, Result1 to Result4 have the same values on both rows.

The objective for me is to only extract from the table when i have the same value from City, Name and Family name and when i have more then 1 difference in columns Reult1 to Result4.

Example. If my table got:
The query result would return:
Query return
How can i do that?

Thank you for your help
