This prompt reminded me of what got me hooked on genealogy seven years ago. I saw #TartanDay trending on Twitter and I had an hour to kill, so I thought I’d trace my Scottish ancestry.
Yeah, I’m still looking for those immigrant ancestors!
Over the years of searching, I have realized that my family is woven together like fabric. Instead of nice, straight lines, like a tartan, some of mine are rather tangled and perhaps a bit psychedelic. Someday, I should do that crime-show trick of using different colored strings on a bulletin board, just to see how tangled it gets!
I still have hope that someday I’ll trace all my ancestors back to the old country(ies) and perhaps, finally, I’ll be able to celebrate Tartan Day with my tartan, instead of just marking it as the anniversary of my genealogical journey.

I like your metaphor. I do hope you find your tartan!
