Your request is a bit ambiguous, notably the "how can I populate" part. But I've made some assumptions and created the attached as an example--only that--of how one might approach this.
On the left there's a table in columns A-C that you would, to use your term, "populate" with a history of donations, dates, names and amounts. In the center, a formula extracts the unique names in column F and then another formula in G provides the total given by each person....this allows for someone like Tom, in the example, to be counted as over the designated lower limit, even though no single gift was over that limit.
Then I use conditional formatting to highlight those amounts. Showing them all gives you the ability to note that someone like Francis, in the example, is only one dollar short of the limit.
To give extra flexibility, I use cell I3 as a spot where you can change your lower boundary, should you want to,
