John: I have not seen any replies yet on list to your July 31 plea for help. My reply will not help much. Neither Arthur Sisley nor Lucille Robb appear on any of the 1901 UK censuses shown on Ancestry. The birth registers for England and Wales between 1901 and 1915 list no births for either of them, nor do the marriage registers list a marriage between them. It is as though they never existed - certainly in England and Wales - though Robb is also a common Scots name so she may have been born in Scotland. One thought - if he was a stretcher bearer in WW1 could Arthur have come over with Australian/New Zealand/South African/American/Canadian troops and settled in England after the war? Another possibility - did they in fact marry. Lucille may have been deserted by her husband and divorce was difficult to obtain in those days, especially for catholics. They may just have been common law husband and wife? Sorry not to have been any real help but it may give you some idea of where to look. Have you tried checking electoral registers for the address at which son Anthony was born. Regards. John Cain 10370.
