Your mission, should you decide to accept it, and I hope that you do, is to:
1) Think about how you want your gravestone to look. What do you want on it as a genealogist? As a child, sibling, parent, spouse, friend? Maybe some sort of witty saying?
2) Tell us about it in text, or create your own gravestone using the online services of companies like Headstones and Memorials. Remember that you have only a limited space to work with and that the bigger they are, the more costly they are.
3) Show us your stone, or what you would put on the stone, in your own blog post, in a comment to this post, or in a Facebook status or comment.
As a genealogist, I want our names to be complete (with Linda's maiden name), and with full birth and death dates. I want a short sentimental statement about each of us, and one about both of us. I also don't want it to break the bank, or to be very ostentatious (I think an in-ground grave marker or wall inurnment works well).
I used the Headstones and Memorials site to create this in dark granite:
This was very easy to do online - you choose a format, a marker material, what you want on it, the border design, press a button and voila! you can see what you created.
