Can I use my unused Charitable Donations from previous years for my new husband (we are filing together) even though we weren't married when I donated?

I have charitable donations from when I was single that I didn't claim because my income wasn't high enough for it to make a difference. Now that I am married I wonder if I can use those unused credits/donations on my new husbands tax return since he made significantly more than I did, even though I was single when I made those donations? We are filing together and using our current year donations on his return.
