Hello Helen,
My Sims/Simms line starts in Somerset:
Ralph b abt 1796 Stanton Drew Somerset married Sarah ? b abt 1796, son Ralph was c13/6/1830 Stanton Drew Somerset, he married Mary/Maria Parry b Dudley, abt 1859. I can't find their marriage. Ralph is listed as coal miner. Looked on Free BDM, Family Search, but nothing. They had two children in York, John b abt 1860 Burton York and Sarah b bt 1862 Wasterdale, York, the other children where born Netherton, Worcestershire) George b abt 1865, Maryan b abt 1867 ( my grgr grandmother) Ralph b abt 1870, William b abt 1874, Samul b abt 1878 and Sarah b abt 1880 ( Sarah becomes Laura in the 1891 census) according to the 1881 census. On the 1871 census all the chlidren were said to be b Dudley, Worcsetershire. 1871 & 1881 they are living at 54 Chapel Street and in 1891 they are living at 113 Halesowen Road.
Mary An married my grandfather John Flavell in Dec quarter 1889 Dudley. On the 1891 census Maryan & John Flavell are living Chapel Street.
Perhaps for the 1861 Ralph & Mary/Maria could be in in Wasterdale, York.
Thats all I can tell you at the moment.
