Messes things up as the source of the data is the same :-)
The data is from the same source ie Paul Ysart, the majority of dates pertaining to the Ysart's working history came from the audio taped interview that Paul give to Alison Clarke in 1988 and by this time was 84 years old and I have got on good authority that Paul's memory had deteriorated by that time. It has now be proven that Paul got some of these dates and facts wrong, the main one being the date the Ysart's started at Moncrieff's, he give 1922 when in fact it was 1921.
Where as the interview with The John o Groats Journal in 1972, he clearly states he left Leith Walk Public School in 1918 and that the Ysart's started at Moncrieff 1921,which corresponds with the Moncrieff Glassworks employee ledger.
