Benjamin w. Bristow G71B-6T8
I have some temple dates for this person
I looked up the details and vitals for both Benjamin w. Bristow G71B-6T8 and Benjamin Bristow LDPT-3YQ
They are separate people with different parents different birth and death dates.
You haven't actually said, but I'm assuming you are questioning whether the ordinances are being duplicated.
The answer is no. You are quite safe to arrange for them all to be done, although some are about to have their reservations expire soon.
I hope this answer is what you are looking for.
Looks like I maybe misunderstood your concern from later questions you posted. If you have the dates the query can be escalated to the appropriate department.
