Was a readers digest condensed novel about a poor single woman who had against her employers wishes took in a boy with no family. Later she shows up with a newborn baby girl (who turns out to be her own daughter) who has a small birthmark the shape of a bell, so she named her belle. Time goes on and her 'brother' takes her to the train station and somehow she gets seperated and lost.. She winds up with a family who never had children who adopt her as their own. She grows up and marries an older man (as I remember...) and somehow figures out what happened to her....
Any clues? Was an older readers digest i picked up at a thrift store anywhere from the 50s to 80s i would say, sorry not more specific.

Sounds like Lost and Found by Marilyn Harris

Andria's suggestion of Lost and Found by Marilyn Harris matches your description. What do you think?

On Christmas Eve, 1930, in America's dust bowl, a young woman delivers her baby alone. Plain, warmhearted Martha Drusso takes the downy-haired infant she names Belle to raise as her own, along with another orphan in her care, a little boy named R.C.
But when Belle is three, her stepbrother mistakenly puts her on a train bound for Los Angeles, then leaves to get her a treat. The train takes off, and Belle is pitched into a child's worst nightmare: a series of orphanages and foster homes. When she is adopted into a loving Japanese-American family, it seems Belle's troubles are over -- until World War II breaks out. Never defeated, Belle is adopted again, and her beautiful singing voice ultimately leads her to Hollywood, and to love and marriage.
