As long as you do not put your information into the body of your question, and responses, your name and email do remain private.( some smartphone replies automatically include a name, so check that yours does not). Only the expert, and the system,‘sees’ the email to send you our replies.
Would you please pull a plant with flowers, leaves and seed head, lay it out flat and photograph it on a smooth plain background( not paper towel since the texture throws the focus off) so we see the way the leaves are arranged on the stem? Include a coin or ruler in the shot so we can see the scale. This is so we can be sure which species of forget-me-not you have.

They are neither flowering nor seeding at this time. IO found a 2 year old picture of their flowering and they are a light blue flower.

However, looking a the photos of the plant you picked, I think it may be Creeping Charlie (Glechoma hederacea) also known as Ground Ivy. The leaves match those of creeping charlie as they are lobed and opposite in the stem, NOT characteristic of the Myosotis genus. Control of Creeping Charlie is a multi-season exercise, maybe even taking several years. Trichlopyr is a more effective herbicide than 2,4-D. More info in the attached links:

Thank you for the information. They are definitely Mysotis perennial (maybe strong). They may have been imported as they were intentionally planted in a garden next to the lawn but spread into the lawn. Although the leaves look similar to creeping charlie, they are much smaller, less than a 1cm while creeping Charlie's leaves are 2 to 2.5 cms. Creeping charlie has been easy to wipe out using Ortho Weed B Gone (Trichlopyr) chickweed , clover etc. Wild violets 2nd as easy and clover a little stubborn, but easy to pull out by hand. But it has no effect on these forget-me-nots.
The plant is a dicot and should be succeptable to applications of a broadleaf herbicide preferably in September, but I haven't been able to find any specific recommendations. More info in the attached link:
