Really appreciate answers re Green Swamp - thank you one and all. So now I know where it was and that it was a property. I found the cert I referred to - marriage between John WYKES, Labourer, Bachelor of Green Swamp and Ann WARK, Servant, Spinster, of Green Swamp; 1872; Presbyterian; Witnesses Charles E JOHNSON and sister of bride, Elizabeth MCALLUM [sic].; place of marriage - residence of Richard SIMS, Green Swamp, Dis of Mudgee. So, possible, that SIMS was owner of property called Green Swamp and John and Ann both worked there. John and Ann had about 10 children mostly born Tichborne/Parkes. But haven't been able to find out any more about John WYKES - no parents on marriage cert. Can't afford transcriptions yet. I don't know why?? but my family history budget is always over spent??!! Would appreciate any info about WYKES. Thank you again re Green Swamp everyone. Alice.
