Looking for Descendants of Robert Euphemia Grant Glasgow Lanark Scotland

Robert Grant and Euphemia Knox married on the 9th August,1822 in Barony, Lanarkshire, Scotland. They had the following children: Janet McFarlane Grant B.15 Feb,1824
Margaret Grant B.9 Mar,1826
John Grant B.16 Jan, 1828
James Knox Grant B.28 May, 1830
Archibald Grant B.18 Aug, 1832
Margaret Grant B.20 Jan, 1836
Robert Grant B.14 Jan, 1838

All the children were born in Barony, Lanark, Scotland. John Grant went to the USA in about 1845 and James Knox Grant ended up in New Zealand via Australia. I am going to be in Glasgow August 2013 and would love to meet up with any distant relations.
