Hi Colin
Thanks for the offer of a gedcom,I will email you.
Your tree is not wrong,hopefully I can explain although it will be a bit long winded
Jane Douglas and Jane Muir Falla are one and the same.Jane Muir Falla b 8th May 1857, Dryfesdale,Bridge,Dumfriesshire to mother Christina Falla,Jane Muir Falla was classed illigitimate. On Janes birth record, below mothers name is Domicile, Dunsdalehaugh Parish of Selkirk, Dunsdalehaugh helps to confirm its the correct Christina Falla as Christina married George Fairbairn in Aug 1865 Selkirk and they lived at Dunsdale cottages according to census records, also Christina's pre married life was at Dunsdale Cottages since at least 1841 census.I do not have the full picture after Jane Muir Falla's birth, cannot find her on 1861 census and on the 1871 census there is a Jane Douglas of the correct age born in Dryfesdale living in Dryfesdale with five others, no relations and of varying ages
by 1881 she is married to John Richardson with son David,1891 with husband John children David,Agnes,William,Andrew and James,1901 husband John and children David,Agnes,Andrew,James Samuel and Thomas.Husband John Richardson according to death record died 24 May 1912, Lochside,Lochmaben married to Jane Douglas,son William as informant, Johns Parents given as David Richardson/Agnes Little,Davids occ as blacksmith.Jane died 17 May 1924,Lochside,Lochmaben widow of John Richardson (farmer),Janes parent as Christina Fallas no father son A richardson as informant.
I will mention just uncase you are interested,Christina appears to have a 2nd illigitimate child Walter Muir Falla b1854 Selkirk and living with mother Christina and grandparents Walter & Elizabeth no sign of Jane Muir Falla on 1861 census
I would love to find out why Jane Muir Falla aka Douglas aka Richardson did change her name,a mystery I wish I could solve.When checking on Freecen I noticed there was a couple of Douglas families living at Dunsdalehaugh in 1851 gone by 1861,Jane was born 1857 a possible maybe there
I hope above makes sense,probably as clear as mud
Im glad the rest of the tree was straight forward
