Try lard? Our great grandmas never had Crisco, they used lard or butter.

Our great grands worked hard, never heard of partially hydrogenated oils, walked everywhere, sugar was a rare treat which is why desserts were so spectacular. Lard is probably better for us than Crisco, it's a food made from real food, no partially hydrogenated stuff.

Start a new tradition with a dessert that's healthier like a fruit tart, or almond milk jello with fruit or lychee compote.

My Mom has tried to make her famous pies with alternatives but found nothing beat butter. Have a slice, have two, enjoy. It's history, it's your family, enjoy. They might not want to do intervals with you next week but suggest you all take a walk in the neighborhood to see Xmas lights.
