Drysdale - a Douglas sept

Drysdale is considered a sept of the Douglas clan, but it is quite likely that this was a separate family which existed previous to when the three Douglas brothers adopted the Drysdale name. A sept is a family that can be related to a clan or larger family for various reasons. Usually this came about either through marriage or by a small family seeking protection from a larger and more powerful neighbour.

    It would be interesting to know the connections of the various Drysdales mentioned in the different versions of this story that you have identified.

    Hi William

    Up until about the year 1600 the two respective family lines are defined/limited by available source material and the fact that there were very few Drysdales around at that time.


    Thereafter the growth in the numbers of descendants is exponential and quickly arrives at many thousands of relatives - including many 100s of Drysdales - some lines are obviously unsourced & suspect but the majority are generally OK
    - Note also that there are many people who have not been entered in the FS world tree

    My genealogy program crashes by the time it gets to about the 12th generation of descendants from the Douglas brothers and the same thing happens at the 14th generation of descendants of the Tillicoultry Drysdales.

    I haven't worked out yet if there is any program that can limit family lines to male descendants (Drysdales) only.

    On the last Familysearch download I did - for Drysdales from Tillicoultry circa 1410 - after about 15 hours of download and about 30,000 names, (up until 1895 & 14 Generations) the program gave up.

    Similarly on the last Familysearch download I did - for Douglas/Drysdales of Dollar circa 1448 - after about 10 hours of download and about 13,500 names (up until 1895 & 12 Generations) the program gave up.

    Note although starting at a later date the Douglas/Drysdale names list seemed to be expanding quicker.

    Of course the easy alternative is to trace each individuals family line on the FamilySearch tree back to the root

    Root person in Tillicoultry - Drysdale ID number G2S7-JYJ
    Root person for Dollar - Thomas Douglas ID number YMP4C-15Y

    There are other ways but the limiting factors are the download times from FS and the vast numbers of persons in the later generations (the software - Ancestral Quest - and my PC seem to have trouble with big numbers)

    Still a work in progress

    Best regards
