Ian I've repied to you off list. I think Lockhart's Gap is named after CGN Lockhart and his brother Norman who were among the first squatters to take up a run at Tallandoon. Their application for pre-emptive right which was unsuccessful is adjacent to where the current Lockhart's Gap road joins the Mitta Valley Road. They used this route over the hills with bullock waggons when they went to Melbourne for supplies. CGN Lockhart was a Commissioner for Crown Lands in NSW and was a competent surveyor. I've been researching the Lockhart family, although I'm not related, but would welcome any further information on CGN Lockhart (Charles George Norman). He retired from Wentworth to Tumut, and may have gone back to Europe, but no-one seems to know where he died. Kath R
