I'm struggling at the moment with lines of investigation of a Betts family in Strood/High Halstow and was hoping for some advice.
I've found Elizabeth Mary Betts Christened 27 Sep 1868 Strood F John M Eliza Catherine. I've also found other siblings, William Henry Betts and George Salmon Betts but cannot find any record of a marriage of John and Eliza despite extensive searches on the parish records for the area (many thanks to whoever posted the Cityark link, it's fantastic

.
I've now found a John Betts that was the right age and area born of parents Benjamin Betts and Mary Wood. The strange thing is as I've looked for siblings I've found lots of other children born to a Benjamin and Mary in the same parish but the name appears as Bates.
My quandry is, is this a likely mistake in Parish records Bates/Betts? I have noticed corrections before in the entries before so I know they did make mistakes. Has anyone else had this sort of problem before?
