Old Fine China

These items have been in a box wrapped in newspaper since before I was born (in 1985). These items are from my father's mother and he was born i 1950. He saw his mother use/display these items as he grew up. So I know they are old(er).   I am looking to get an idea about their value, so that we may sell these.  There are a lot of items. 

SOme say "Made In Germany 43" "68"  "73" "83"  they also have a name on them "L. Marston"

Another plate says "MZ Altrohlau CM-R  Czechoslovakia"

"Thiodore Haviland Cimoges FRANCE"

"EST  A 1831  Allertons LTD England Kenilworth Made in England" (with a star)

"E.H. George  J.P/L France"

Fine Bone China Shelley England  Ovington 13216"

There's green depression glass, most of the plates have a floral design, we have two tea sets, very old pie plates, and one particular plate I am interested in. It's white and blue, there's a woman on the front, and the back has a poem  titled "Evangeline" by longfellow. Oval Staffordshire Burslem England. 

There's a green depression glass violin that used to hang on a wall, it is almost 12" tall.
