George,

There are references in Order of Battle data (see Hennessy's "The First Battle of Manassas: An End to Innocence, July 18-21, 1861." Lynchburg, VA: H. E. Howard, Inc., 1989) as well as several others to this effect. The battery, Alburtis', was attached verses being organic to the brigade. Apparently, it was disattached sometime in 1861, but I do not have specific data. Reading what you provided may provide me that information.

Thanks for your prompt response.

Henry
