Hi Monica,
Yes, that's the Walter & family I am related too (Walter's son David b.10 Jan 1829 d.16 Feb 1917 in Tulliallan, was married to Isabella Stewart Gillespie b. 14 Mar 1835 d. 20 Nov 1906 in Kincardine who was my ancestor. Her brother Lawrence Gillespie immigrated to Australia when he was very young (between 1851-61) i.e. 7-17 yrs old so I think he sailed on one the ships which belonged to the McLaren family. The rest of his family, his parents David & Eliza neč Scotland immigrated after Apr 1871, as they disappear and emerge in 1880 in Otago. He was a Carter by trade.
I thought if I found the name of the ship owned by the McLaren family, I could try finding it in NZ shipping arrivals.
I'm afraid I don't know when Walter snr was born, but he was a shipowner by 1822.
I found this on Rootsweb Perthshire- L archives dated May 2003, by Margaret O'Donnell.
