Thank you for the suggestions so far - please keep them coming. I am struggling with the geography and social history of the area, so welcome and value any comments about the place and times. Len has pointed out that the LEADER name is not basically from Co. Clare, and this is borne out by a comment in "Irish Names and Surnames" - WOULFE 1923 who says it is "A late English surname in County Cork". Ancestry's index of Griffith's Valuation lists the name over 600 times, but this includes multiple entries where one person had more than one allotment, and also both Lessors and Lessees ( and there were a few in the latter category). My quick count showed only 4 LEADER's in county Clare, and 2 in Limerick, with the rest in Cork. There were only two occurrences in the Index of Irish Wills (James in Upper Sunville in 1792 and Thomas in Limerick). The 1788 "General Directory of the Kingdom of Ireland" showed John LEADER as a grocer in Ennis, but I could find no mentions in the 1824, 1846 or 1856 directories for Ennis. I had expected to find at least Ellen I had assumed that the LEADEN name was a mis-transcription for LEADER, as it looks that way in Griffiths, but the Baptismal entry is more worrying. I have not seen any parish registers, as I understood that they were only available on microfilm at NLI, and then only from March 1841 for Baptisms and April 1847 for Marriages, so I will need to explore that further, thank you. The Shipping Registers for SA are incomplete, but I do have the one for the "Escort" . Sailing on the Escort from Clare under Remittance Orders, there was one married couple, (both Farm Labourers), 20 Single females ( 1 Dairy Maid, 16 Domestic Servants and 3 Farm Servants) and 21 single males (2 farm servants, 2 Labourers, and 17 farm labourers). I have often wondered whether they were actually from one or more Workhouses, but have not been able to find any information. The only formal programme I have found finished a few years before Catherine was involved. Thank you again, and please keep the suggestions and ideas coming. Robert SLATER South Australia
