I'm currently playing a bit with #Gramps, an open source program for recording genealogical relationships. Now that I have finally collected a critical mass and have become familiar with how the source information is recorded in Gramps, I am quite impressed. I think I can work with this!
My #PhD project is about the ancestors and descendants of ʿAbd al-Qādir al-Jīlānī, a scholar from 12th century Baghdad, who is situated in the center of the chart. He himself is said to be descended from the Prophet Muḥammad, with whose grandfather the chart begins. The chart currently covers the period from around 650 to 1400.
For my dissertation, I am looking at texts in which these lineages are followed up to the 18th century. So there is still a lot to do: add lots of people and compare the information in the various sources I have in front of me!
