"She arrived in 1852 from Doderhult in the county of Kalmar & went into service as a maid at Ragelund."
Records were kept in the parish and not in the village/farm, so it is important to name parishes. Also provide a specific source reference. (Somehow you found or someone else found a record telling the information I quoted from your message. Always tell us where that information was found.)
I think that "Ragelund" must be Rågelund in Landa parish, Halland county. At least some Landa parish records are included in the records for Ölmevalla parish in the time period around 1852.
Your ancestor was listed here as Beata Jakobsdotter Welin.
Döderhult (not Doderhult) is a parish in Kalmar county.
The following record from Döderhult parish lists the piga (female farm worker) Beata Jakobsdotter Welin moving out from Döderhult parish but I see a "till Amerika" (to America) there, and not a destination of Landa parish. I was looking for the location where she had lived in Döderhult parish but I don't see that. Maybe someone else will.
