Rugby XI. Information request.

Do any sporting historians out there have any knowledge of Rugby XI from Kilmarnock?
They seem to have existed between 1889 & 1910, being the first Ayrshire team to reach the Scottish Junior Cup final. They played at Rugby Park and may have been Kilmarnock reserves, but this is not clear.
I do know that the line up for the final, which was lost to Maryhill in 1900, was; McLung, Robertson, Banks, Higgins, Johnstone, Woodburn, McIntyre, Parker, Green, Graham & Aitchison.
