I am the groom mother and would like to ask for help. Peter is my son and Holly his fiance. They`re a young couple that wants to get married but do not have the funds.I am out of work due to dr`s orders and Hollys family has six children.Holly was born without an immune system and has a heart condition.We wish we could give this miracle girl the wedding of her dreams. Raising Peter has been a struggle we`ve even lived in a shelter. I raised him believing in marriage has a holy sacrament . If anyone could help please contact me.
