Duncan, New info. While talking to my 92 year old great-aunt, I got to asking more about the Lamberton side of our tree and she told me that my gg-grandmother's sister Isobella Cochrane (nee Lamberton) was named after her grandmother. I popped down to Auckland library research room and checked the 'Old Parochial Records' files for both Christenings and marriages.Listed in Craigie was the marriage of Alexander Lamburghton to Isobel Brown on 15/3/1797. Children listed to them (all spelled Lamburghton unless noted otherwise)on parochial files are: :Margaretb.1797 :Williamb.1805 :Alexanderb.1807 :John Stirling b.1809 spelled Lambrughton :Catherineb.1811 spelled Lambroughton :Laurenceb.1814
As well as these I also found a few others in Craigie which are listed as having Alexander as father and which seem to fit. These were: :Margaret b.1797 spelled Lambrughton :Thomasb.1798 :Jamesb.1799 :Jeanb.1801 spelled Lambroughton :Margetb.1803 :Isobella b.1806
After finding out all this I phoned g-aunt to ask whether she knew whether Thomas came from a large family; her reply, "Oh yes, at least ten or so."Well, if these are all correct that makes 11 counting the 2 Marg's, and there may still be others.
Also, while hunting at the library I found these varients on the Lamberton name, which I checked with the Scottish Interest Society and have been assured that they would all be pronounced very similarly. LAMOURGHTOUN LAMBOCHTON LAMROCHTON LAMROCHTOUN LAMEROCHTOUN LAMROCKTON LAMROCKTOWN LAMBROUGHTON LAMBROUGHTOUN LAMBOUGHTON LAMBOURGHTOUN LAMBRUCHTON LAMBRUGHTON LAMROUGHTON LAMROUGHTOUN
Hunting using these varients has turned up a couple of missing persons for me, hope they help you as well.
