Since the two Rebeccas shown as Benjamin's sisters are one and the same person (and need to be merged as Pip suggests) who lived into adulthood, you must be referring to Benjamin's daughter Rebecca, whose profile has little information - so she may have died at age 3. Your question implies that you know the location. So, "yes" is our answer to your question. We want to know the location of her grave that shows she died at 3 years of age. Your question implies that you know the location.
