help in ID'ing lily pattern knives

[conuremom]

Hello! I found this forum while trying to determine the origin of my
mother-in-law's sterling silver (butter?) knives (photo is at
http://home.comcast.net/~conuremom/Pics/knife_pics.jpg" onclick="window.open(this.href);return false; ).
I've been unable to find a local copy of any silver ID books, so I've
had to do all my research online.

I've traced them as far as being American, I think they were made by the Watson company, and I think the pattern is "Easter lily". If anyone could confirm that, I'd appreciate it.

Also, is there any way to tell by the markings when
these were made? I know the Watson company kept changing their
trademarks, but I can't find out when they used the three-symbol one.
(note, the hallmarks are not enclosed in circles, nor does it say 'trademark' under them as I've seen in some photos online).

Mom-in-law just inherited these from her late mother. They belonged to
her grandmother, and she'd love to know more about them. Any help you
can supply would be appreciated. I very nearly cut these up to make bracelets for MIL and the grandkids before noticing the hallmarks!
Thanks in advance,

The marks are, indeed, Watson. The mark on your knives was used 1910-1938. Your knives appear to be "Lily", introduced in 1902.
