Well done.
I have often found it may require more than one search. Last year an elderly man asked me to look for his ring. They had been married 48 years and he was heartbroken.
I didn't find the ring and for 36 hours all I could do was remember his disappointment. So two days later I woke up determined to find that ring. Well after 6 hours I finally found it. It was in a very challenging location.
As a thank you I was given permission to search another location. His family has owned a 70 acre area nearly 100 miles away but in the late 1800s two sea captains had lived there. I was working around their cabin and found a twin for his ring. I called his wife and asked if she had lost her ring and learned HE had lost his first wedding ring over 30 years ago.
I told her it was coming home.
