Hi Marilyn, I'm not sure I can be of much help to you, but I'll give you all the information that I have. Also, you'll note that I've copied both the PETRIE-Scotland mailing list and the Caithness mailing list on my emails! The information on Isabella PETRIE and her marriage to Alexander LANARCH comes from Norma Thain, the person who is the coordinator (list manager)of the PETRIE-Scotland list....but more than that she is a very kind lady who never seems to forget that we're out there searching and she is kind enough to send a message to any of us if she comes across information that is of interest! Recently she sent the following information: Hi Julie & George, Found this certificate for a previously unknown daughter of Donald Petrie & Jane Dallas...... Marriage Certificate Ref:  1861   St. Andrews, EDINBURGH   Page 19   Entry 38 (source Scottish Records Office) On 1st February 1861 at 15 Elder Street, Edinburgh (after banns of Free Church of Scotland) ALEXANDER LARNACH Waiter Bachelor age 25 of 15 Elder Street, Edinburgh Parents: ALEXANDER LARNACH  - Hotel Keeper   - deceased ELIZABETH LARNACH  ms  GRAY ISABELLA PETRIE Domestic Servant Spinster age 24 of 15 Elder Street, Edinburgh Parents: DONALD PETRIE  - Farmer JANE PETRIE  ms DALLAS Witnesses: JAMES BERRY CICILIA CORMACK ********** Cheerio Norma That's the information that I have concerning your family and Isabella PETRIE, Marilyn. Some time back Norma was able to find a George PETRIE (the oldest brother of Isabella PETRIE) on the death certificate of his mother, Jane DALLAS who died in Wick in 1855. Because of the detail on the 1855 death certificate she found that the children were all listed, the oldest, George born in Glasgow about 1817 and the youngest Isabella, born in Wick about 1835. I'm still not sure if this George PETRIE is the father of my great grandmother Catherine PETRIE, and if I'm part of the DALLAS line. You would think that I would have found Catherine on the 1851 census for Wick, but so far I haven't had any luck. I have found Catherine on the 1861 census for Wick, where she's listed as servant to the BREMNER family (cowherd) at 12 years of age! I keep hoping that I'll come across her in the 1851 census but so far there's been no luck! If you want what I have on the Dallas family after you've determined if this is your Isabella PETRIE, please let me know! George Weston Suisun, CA USA
